Nearly 100 people were arrested after protesters gathered at Trump Tower in Manhattan Thursday to denounce the arrest of Mahmoud Khalil, a Palestinian activist detained by ICE over his involvement with pro-Palestinian demonstrations at Columbia University.

Some protesters held signs that read "Fight Nazis not students," "Free Mahmoud free Palestine" and "You can’t deport a movement."

Police arrested nearly 100 protesters demanding the release of Syrian national Mahmoud Khalil during a sit-in protest at Trump Tower in Manhattan on Thursday.

We want to be visible,” Khalil said last April. Now that visibility has helped make him the face of President Donald Trump's drive to punish what he calls antisemitic and “anti-American” campus protests.

Former Columbia University student activist Mahmoud Khalil remains in an immigration detention center in Louisiana. Protesters nationwide are calling for his release, saying the federal government is violating his First Amendment rights by seeking to deport him amid the White House's crackdown on students and alleged "agitators" protesting Israel's war with the terror group Hamas.

Nearly 100 arrests were made at Trump Tower in Midtown after hundreds of Jewish New Yorkers and friends packed into the lobby to protest the arrest and detainment of Columbia graduate Mahmoud Khalil.Video taken Thursday afternoon showed officers handcuffing some of the demonstrators associated with Jewish Voice for Peace -- an organization that is critical of many of Israel's policies regarding Palestinians.

After a hearing on Wednesday, the Palestinian activist’s wife accused the Trump administration of kidnapping him.
