New York City Councilmember Vickie Paladino joins 'Fox & Friends Weekend’ to discuss the arrest of pro-Palestinian student Mahmoud Khalil, and the Trump administration's crackdown on anti-Israel protests.

Between classes, when throngs of students stream into and out of Columbia University ’s campus, the security lines can back up like a TSA checkpoint. There’s a switch-back path of metal fencing that leads into a white tent, where two sets of guards check and then swipe campus ID cards before letting students in and out.

Columbia University says it has expelled or suspended some students who took over a campus building during pro-Palestinian protests last spring and temporarily revoked the diplomas of some students who have since graduated.

Federal agents searched two student residences at Columbia University, its interim president said, a week after immigration agents detained Mahmoud Khalil, a leader of last year's campus protests, who the Trump administration wants to deport.

The Department of Homeland Security arrested a second student involved in the protests at Columbia University.

A top U.S. Justice Department official says the department is investigating whether Columbia University concealed “illegal aliens” on its campus.

Agents with the Department of Homeland Security searched two university residences with a warrant Thursday evening. No one was arrested and it was unclear whom the authorities were searching for.
