New Yorkers Protest as White House Defends Arrest of Mahmoud Khalil at Columbia

As hundreds of demonstrators made their way through Lower Manhattan on Tuesday to protest the detention of a prominent pro-Palestinian activist at Columbia University, the White House defended the arrest and rebuked the school for what it called lack of cooperation.The activist, Mahmoud Khalil, was a leader of student protests on Columbia’s campus and often served as a negotiator and spokesman.Mr.

Khalil, 30, who is Palestinian and was born and raised in Syria, is a legal permanent resident of the United States and is married to an American citizen.He was arrested on Saturday and transferred to detention in Louisiana.A spokeswoman for President Trump, Karoline Leavitt, told reporters on Tuesday that the government had the authority to revoke Mr.Khalil’s green card under the Immigration and Nationality Act.“This is an individual who organized group protests that not only disrupted college campus classes and harassed Jewish American students and made them feel unsafe on their own college campus, but also distributed pro-Hamas propaganda fliers with the logo of Hamas,” she said.Her remarks came a day after Mr.

Trump vowed that the apprehension of Mr.Khalil was “the first arrest of many to come.”Some free speech groups and civil rights activists have questioned the legality of Mr.

Khalil’s detention, which his lawyers have challenged in court.On Tuesday, some New York Democrats expressed concern about the arrest.

But Mayor Eric Adams shrugged off questions about it at a City Hall news conference, saying that the federal government, not the city, had authority over the matter.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.If you are in Reader mode please exit and log into your Times account, or subscribe for all of The Times.Thank you for your patience while we verify access.Already a subscriber? Log in.Want all of The Times? Subscribe....
