Trump says ICE arrest of Palestinian activist the 1st of 'many to come'
President Donald Trump on Monday weighed in on the ICE detention of Mahmoud Khalil, a leader in Columbia University's encampment movement who he said was a "Radical Foreign Pro-Hamas Student."
"We know there are more students at Columbia and other Universities across the Country who have engaged in pro-terrorist, anti-Semitic, anti-American activity, and the Trump Administration will not tolerate it. Many are not students, they are paid agitators. We will find, apprehend, and deport these terrorist sympathizers from our country -- never to return again," Trump posted on Truth Social.

Trump added that the White House "expect[s] every one of America's Colleges and Universities to comply."
ICE arrested Khalil over the weekend, claiming that his student visa had been revoked, according to attorney Amy Greer in a statement to ABC News. However, Khalil is in the United States on a green card and not on a student visa, Greer said.
