“You have – of the witnesses today of the major cities, you have publicly stated that you were willing to work with ICE on detaining the most criminal illegals. And I want to thank you for that,” Comer said before asking Adams whether New York is a sanctuary city.

“Based on our classification, yes,” Adams responded to the question, which was the only one posed by Comer. 

Each mayor leads a “sanctuary city” a term for policies that limit local cooperation with federal immigration enforcement. The mayors continued to make the case that their cities follow federal immigration laws and that their policies ensure undocumented immigrants can report crimes and utilize city services without fear of deportation.

Republicans accused the mayors of defying President Trump’s immigration agenda and releasing dangerous criminals onto the streets. Rep. Comer used his opening statement to depict the four cities as dangerous and full of crime, calling them “a public safety nightmare.”

We cannot let pro-criminal alien policies of obstructionist sanctuary cities continue to endanger American communities and the safety of federal immigration enforcement officers,” Comer said.

The Kentucky Republican then turned to Mayors of Boston and Chicago to ask them about whether they would turn over immigrants facing charges to federal immigration authorities. Both mayors said their cities would follow the law, but neither said they would proactively turn over an immigrant to ICE if they had been detained on state charges.

“The point that we’ve got to iron out today is that we have to have cooperation,” Comer said. “It is federal law to turn over those illegal criminals to ICE, and we have heard reports and many of you have said publicly that you were going to obstruct that.

In his opening statement, Adams argued New York City can still be a sanctuary for immigrants while also obeying federal laws.“I’m here today to testify on how New York City can continue to reduce crime, even as a sanctuary city. 

“To be clear, a sanctuary city classification does not mean our city will ever be a safe haven for filing criminals. It also does not give New York City the authority to violate federal immigration laws,” Adams said.

Adams’s testimony comes as the Department of Justice has called for the mayor’s criminal bribery and fraud case to be dismissed. The DOJ said in a filing that the case would impede Adams’s ability to carry out his duties as mayor and brought an “unacceptable” threat to safety and “related federal immigration initiatives.” Adams has since appeared in a joint interview on Fox News with Tom Homan, Trump’s border czar, to announce he would allow ICE to reopen an office at Rikers Island for the first time in more than a decade.

Multiple Democrats focused their questioning on Adams and accusations that he engaged in a quid prop quo with the Trump administration to have his federal corruption charges dropped in exchange for his cooperation on immigration.

“There’s no deal, no quid pro quo, and I did nothing wrong,” Adams said to in response to similar questions to a variety of Democrats.

Rep. Robert Garcia (D-CA) accused Adams of “selling out New Yorkers” and called on him to resign.

“I personally agree with the majority of New Yorkers and think Mr. Mayor that you should resign, you should do the right thing, step down and resign today,” Garcia said.

Watching some of the sanctuary city hearing while on a flight. One Democrat congressman accuses Mayor Adams of “selling out New Yorkers” while making a deal with Tom Homan. Simply disgusting. Mayor Adams is trying to protect New Yorkers from violent illegal aliens. He is trying…

Tom Homan defended Adams on social media calling Garcia’s allegations that Adams was “selling out New Yorkers” to save himself from prosecution as “simply disgusting.”“Mayor Adams is trying to protect New Yorkers from violent illegal aliens,” he wrote. “By working with ICE, lives will be saved. FACT!”

Rep. Gerry Connolly (D-VA), the ranking member of the panel, slammed his GOP colleagues for shielding President Donald Trump from accountability and the rule of law, making a veiled dig at Mayor Adams.

“President Trump’s Department of Justice has tried to force the conditional dismissal of very serious charges against one of our witnesses here today in exchange for that witness’s total and complete submission to the radical immigration agenda being propounded by the administration,” Connolly said during his opening remarks. “The DOJ has done so over the objections of a Republican acting US attorney who President Trump appointed.”

Connolly went on to mention recent comments from Homan in a speech to the Conservative Political Action Conference (CPAC), in which Homan slammed Boston’s police commissioner, saying there are at least nine accused “child rapists” in jail who local authorities won’t turn over to ICE. Homan went on to promise to “bring hell” to Boston. 

“Let’s talk about Tom Homan. Shame on him for lying about my city, for having the nerve to insult our police commissioner, who has overseen the safest Boston has ever been in anyone’s lifetime,” Wu said in response. “Bring him here under oath, and let’s ask him some questions.”

Rep. Lauren Boebert (R-CO) got into a heated exchange with Denver Mayor Johnston about an ordinance preventing city employees from talking to immigration authorities. She asked Johnston to join her in demanding Colorado repeal those laws.

“I do not believe the detainer law needs to be changed,” Johnston said.

Boebert went on to ask Johnston if employees would get fired for talking with “anyone from the EPA” or “Health and Human Services,” and then asserted that they would “only be fired for talking to federal law enforcement officers.”

“No, that’s incorrect, Congresswoman – our city employees do in fact communicate with ICE, we coordinate multiple things with ICE, for instance if there is a violent criminal warrant in the city,” Johnston said before being cut off by Boebert, who rejected his argument.

“There are issues happening before warrants are issued and local law enforcement officers are unable to coordinate,” Boebert responded.

Democrats on the panel continued to point out that the Trump administration and Congress have not addressed voter’s top issue: the economy. Some of the mayors found opportunities to put Republican members on defense. Mayor Michelle Wu pushed back against suggestions that undocumented immigrants pose the biggest threat to Boston.

“If you want to make us safer, pass gun reform, stop cutting Medicaid, stop cutting funds for veterans,” Wu said in response to questioning from Rep. Paul Gosar (R-AZ).

In response to criticism of mass deportation from Wu, Comer offered a surprising comment, saying “I don’t think anyone’s calling for mass deportation,” Trump himself has promised the “largest domestic deportation operation in American history” during his joint address to Congress on Tuesday night and renewed his ask for more funding to carry out his immigration agenda.
