What is a green card? Lawyer breaks down Mahmoud Khalil case
KNOXVILLE, Tenn. (WATE) — With the case of a Columbia University graduate making national headlines, some may be left wondering what a green card is or how someone who is a 'permanent resident' can be deported. In this week's Ask Isaacs, 6 News' Lori Tucker and Attorney Greg Isaacs discuss the Mahmoud Khalil case.
In the United States, a green card, or what is sometimes called a 'permanent resident card' allows someone who is not a citizen to live and work permanently in the U.S., according to U.S. Citizenship and Immigration Services. Some of the common individuals who are eligible for green cards include:
Spouses of a U.S. citizen
Academic professionals
Religious workers
International media broadcasters
Asylees (people seeking asylum) or refugees
Victims of crime or human trafficking.
In the case of Mahmoud Khalil, he came to the United States under a student visa in 2022 to pursue a graduate degree at the University of Columbia. In 2023, he married his wife, who is a U.S. citizen, and became a legal permanent resident last year.
What to know about Mahmoud Khalil, the Columbia protester arrested by ICE and facing deportation
Khalil was detained by U.S. Department of Homeland Security on Saturday, March 11 in upper Manhattan. The agency has since accused Khalil of leading 'activities aligned to Hamas, a designated terrorist organization.'
One of the perplexing points of the case is that agents told Khalil's pregnant wife that he was being detained because his student visa had been revoked, and that his green card was also revoked, a lawsuit from Khalil's attorneys filed challenging his detention claims.
While Khalil has not been charged with a crime, White House press secretary Karoline Leavitt said on Tuesday that the administration is moving to deport him through a section of the Immigration and Nationality Act that gives the secretary of state the power to deport a noncitizen on foreign policy grounds. Khalil was a leading pro-Palestinian activist at Columbia University, President Donald Trump has argued on social media that Khalil is a 'Radical Foreign Pro-Hamas Student.'

Generally, green card holders can be deported if they are convicted of certain crimes, such as using or abusing drugs, failing to advise immigration authorities of a change of address within 10 days of the move, or providing material support to a terrorist group. The Isaacs Law Firm explains that they can also be deported without a criminal convictions if they are proven to abuse drugs or be addicts.
Some convictions are also grounds for a person's green card to be revoked and for them to be deported. Those offenses include:
Aggravated felonies – such as murder, drug trafficking or rape
Crimes involving 'moral turpitude' or that are considered 'immoral, unethical or [an] unjust departure from ordinary social standards' – such as fraud, theft, or assault
Any firearm offense
Trafficking
Or crimes of domestic violence, stalking, violation of a protective order, or child abuse, neglect or abandonment.

UN to vote on resolution demanding Gaza ceasefire, hostage release and aid access
UNITED NATIONS (AP) — The U.N. General Assembly is expected to vote Thursday on a resolution demanding an immediate ceasefire in Gaza, the release of all hostages held by Hamas, and the opening of all Israeli border crossings for deliveries of desperately needed food and other aid. The resolution, drafted by Spain and obtained Wednesday by The Associated Press, 'strongly condemns any use of starvation of civilians as a method of warfare.' Experts and human rights workers say hunger is widespread in Gaza and some 2 million Palestinians are at risk of famine if Israel does not fully lift its blockade and halt its military campaign, which it renewed in March after ending a ceasefire with Hamas. Last week, the U.N. Security Council failed to pass a resolution demanding a ceasefire in Gaza and calling on Israel to lift all restrictions on the delivery of aid. The United States vetoed the resolution because it was not linked to the release of the hostages, while all 14 other members of the council voted in favor. There are no vetoes in the 193-member General Assembly, where the resolution is expected to pass overwhelmingly. But unlike in the Security Council, assembly resolutions are not legally binding, though they are seen as a barometer of world opinion. After a 10-week blockade that barred all aid to Gaza, Israel is allowing the United Nations to deliver a trickle of food assistance and is backing a newly created U.S. aid group, which has opened several sites in the center and south of the territory to deliver food parcels. But the aid system rolled out last month by the Gaza Humanitarian Foundation has been troubled by near-daily shootings as crowds make their way to aid sites, while the longstanding U.N.-run system has struggled to deliver food because of Israeli restrictions and a breakdown of law and order. The draft resolution being voted on Thursday references a March 28 legally binding order by the top United Nations court for Israel to open more land crossings into Gaza for food, water, fuel and other supplies. The International Court of Justice issued the order in a case brought by South Africa accusing Israel of acts of genocide in its war in Gaza, charges Israel strongly denies. The resolution stresses that Israel, as an occupying power, has an obligation under international law to ensure that humanitarian aid reaches those in need. It reiterates the assembly's commitment to a two-state solution to the Israeli-Palestinian conflict, with the Gaza Strip as part of a Palestinian state. The assembly is holding a high-level meeting next week to push for a two-state solution, which Israel has rejected. The resolution supports mediation efforts by Egypt, Qatar and the United States aimed at implementing a January ceasefire agreement. When the U.S. vetoed last week's Gaza resolution, acting Ambassador Dorothy Shea said it would have undermined the security of Israel and diplomatic efforts to reach a ceasefire 'that reflects the realities on the ground.' Like the failed Security Council resolution, the resolution to be voted on Thursday also does not condemn Hamas' deadly attack in southern Israel on Oct. 7, 2023, which ignited the war, or say the militant group must disarm and withdraw from Gaza. Both are U.S. demands. The Hamas-led militants killed around 1,200 people, mostly civilians, and took 251 hostage. About 55 hostages are still being held. Israel's military campaign has killed over 55,000 Palestinians, according to Gaza's Health Ministry. It says women and children make up most of the dead, but doesn't distinguish between civilians and combatants. Israel says it has killed more than 20,000 militants, without providing evidence.

Orders Revealed for Trump's Army Speech: ‘No Fat Soldiers'
Directives for the Army audience at President Donald Trump's speech at Fort Bragg on Tuesday included one frank line: 'No fat soldiers.' Attendees were also given the option to not be in the audience at all if they disagree with the Trump administration, reported. 'If soldiers have political views that are in opposition to the current administration and they don't want to be in the audience then they need to speak with their leadership and get swapped out,' read the unit-level note to troops in the 82nd Airborne Division. In his speech, which on paper was meant to mark the Army's 250th birthday, Trump unleashed blatantly political attacks on former President Joe Biden, California Gov. Gavin Newsom, and Los Angeles Mayor Karen Bass. The criticisms were met with agreement from the audience, in the form of booing, in what called a 'a shocking and rare public display of troops taking part in naked political partisanship.' The outlet said service officials declined to comment on whether any potential discipline for booing—or cheering—soldiers was in store. One commander at Fort Bragg—the name of which Trump restored earlier this year—anonymously called the event 'shameful.' 'This has been a bad week for the Army for anyone who cares about us being a neutral institution,' the person said. 'This was shameful. I don't expect anything to come out of it, but I hope maybe we can learn from it long term.' An 82nd Airborne noncommissioned officer said, 'I bet none of those soldiers booing even know the mayor's name or could identify them in a lineup; they're nonexistent in the chain of command.' They added: 'So, any opinion they could possibly have can only be attributed to expressing a political view while in uniform.' Yet Pentagon spokesperson Sean Parnell didn't see an issue. 'Believe me, no one needs to be encouraged to boo the media,' he said in a statement to 'Look no further than this query, which is nothing more than a disgraceful attempt to ruin the lives of young soldiers.' Another problematic occurrence Tuesday was the selling of pro-Trump items and apparel on Army property, which 'likely' violates Defense Department regulations, noted. Parnell did not address this issue when asked. Trump's speech wasn't the only instance in which the optics of soldiers near him was front-of-mind. In 2019, Trump reportedly told then-Chairman of the Joint Chiefs of Staff Mark Milley during a welcome ceremony for injured Army captain Luis Avila that 'no one wants to see' wounded soldiers. A few years prior, Trump also reportedly said that he didn't want 'wounded guys' in his planned military parade in Washington, D.C., which ended up being scrapped. This Saturday's costly parade, purportedly to honor the Army's 250th anniversary, is on Flag Day, which is also Trump's birthday.

Judge says government must release Mahmoud Khalil
The Brief A federal judge ruled that ICE must release Mahmoud Khalil, a Palestinian student and recent Columbia graduate, unless the government appeals within 40 hours. Khalil, a green card holder, was detained in March by DHS agents and held in Louisiana for his involvement in pro-Palestinian campus protest. The Trump administration argues Khalil's activism threatens U.S. foreign policy interests, but has not alleged criminal conduct or presented evidence linking him to extremist groups. NEW YORK - A federal judge has ruled that the government must release Mahmoud Khalil, the former Columbia University student who has been in ICE custody for over two months over pro-Palestinian demonstrations. The government has 40 hours to appeal the decision; until then, Khalil will remain in custody, likely through at least Friday. MORE: Mahmoud Khalil update: Government must provide evidence in case Wednesday, judge says MORE: Over 80 arrested after anti-ICE protest erupts in NYC: 'We will not tolerate chaos' MORE: Lawyers for Mahmoud Khalil urge judge to release him from ICE custody in Louisiana "The court's decision is the most significant vindication yet of Mahmoud's rights," said Ramzi Kassem, co-director of CLEAR, a legal nonprofit and clinic at the City University of New York that represents Khalil. "But we aren't out of the woods until Mahmoud is free and back home with his wife and child." Timeline The Trump administration has been pushing to deport Khalil and other student demonstrators over their involvement in campus protests against Israel. "We gave you a visa to study and earn a degree, not to become a social activist and tear up our university campuses," Sen. Marco Rubio said shortly after Khalil's arrest. Khalil, a 30-year-old Palestinian by ethnicity who was born in Syria, was arrested back on March 8 in New York and taken to a detention center in Louisiana. The immigration detention center in Jena, Louisiana, is thousands of miles from his attorneys and wife (a U.S. citizen), who gave birth to their first child while he was in custody. He recently finished his coursework for a master's degree at Columbia's school of international affairs. The backstory Khalil has adamantly rejected allegations of antisemitism, accusing the Trump administration in a letter sent from jail last month of "targeting me as part of a broader strategy to suppress dissent." "Knowing fully that this moment transcends my individual circumstances," he added, "I hope nonetheless to be free to witness the birth of my first-born child." Facing a deadline from an immigration judge to turn over evidence for its attempted deportation of Khalil, the federal government submitted a brief memo, signed by Secretary of State Marco Rubio, citing the Trump administration's authority to expel non-citizens whose presence in the country damages U.S. foreign policy interests. The two-page memo, which was obtained by the Associated Press, does not allege any criminal conduct by Khalil. Rather, Rubio wrote, Khalil could be expelled for his beliefs. Judge Farbiarz had ruled earlier that expelling Khalil from the U.S. on those grounds was likely unconstitutional. Big picture view The Trump administration has pulled billions of dollars in government funding from universities and their affiliated hospital systems in recent weeks as part of what it says is a campaign against antisemitism on college campuses, but which critics say is a crackdown on free speech. To get the money back, the administration has been telling universities to punish protesters and make other changes. The U.S. government has also been revoking the visas of international students who criticized Israel or accused it of mistreating Palestinians. At the time of Khalil's arrest, a Department of Homeland Security spokesperson accused Khalil of leading activities "aligned to Hamas," referring to the militant group that attacked Israel on Oct. 7, 2023. But the government has not produced any evidence linking Khalil to Hamas, and made no reference to the group in their most recent filing.
