U.S. Muslim and Jewish advocacy groups criticized President Donald Trump on Wednesday for referring to the top Senate Democrat, Senator Chuck Schumer, as a Palestinian, with the organizations saying the president used the term as a slur.

Donald Trump alleged Wednesday that Chuck Schumer, the top Democrat in the Senate, is not Jewish. “Schumer is a Palestinian, as far as I’m concerned. You know, he’s become a Palestinian,” the president said in the Oval Office on Wednesday.

Palestinian activist Mahmoud Khalil will remain in an ICE detention facility in Louisiana after his first court hearing to fight a potential deportation by the Trump administration.

Prominent Palestinian activist Mahmoud Khalil will remain in an ICE detention facility in Louisiana for now following a procedural hearing in New York, days after he was arrested by federal officials at his Columbia University residence in an attempt by the Trump administration to deport him.

A federal judge said Khalil will remain in the U.S. as the court weighs a challenge to his planned deportation, as President Donald Trump says his arrest will be the first of many.
