NEW YORK (AP) — Columbia University’s main campus will switch to hybrid learning for the rest of the semester amid protests over Israel’s war with Hamas that have roiled colleges across the U.S. University officials announced the move late Monday after more than 100 pro-Palestinian demonstrators who had camped out on Columbia’s New York City campus were arrested last week. Students have protested against Israel’s war in Gaza at many campuses. That includes New York University a few miles south of Columbia. An encampment there swelled to hundreds of protesters, and police began to make arrests Monday night. A police spokesperson said he did not know how many NYU protesters had been arrested.

NEW YORK (AP) — The National Enquirer's former publisher is expected to return to the stand in Donald Trump's historic hush money trial as testimony continues in the first-ever criminal trial against a former U.S. president. David Pecker was the first and only witness Monday following opening statements. Prosecutors say Pecker worked with Trump and Trump’s then-lawyer, Michael Cohen, on a “catch-and-kill” strategy to buy up and then spike negative stories during the 2016 campaign. Testimony resumes Tuesday. It's the first of Trump's four indictments to go to trial and the first criminal trial against a former U.S. president. He has pleaded not guilty to 34 felony counts.

WASHINGTON (AP) — The Senate is returning to Washington to vote on $95 billion in war aid to Ukraine, Israel and Taiwan. Lawmakers on Tuesday are taking the final steps in Congress to send the legislation to President Joe Biden’s desk after months of delays and contentious internal debate over how involved the United States should be abroad. The $61 billion for Ukraine comes as the war-torn country desperately needs new firepower and as Russian President Vladimir Putin has stepped up his attacks. Soldiers have struggled to hold the front lines as Russia has seized the momentum on the battlefield and forced Ukraine to cede significant territory.

PARIS (AP) — French police have evicted migrants from a makeshift camp in Paris a few steps away from the Seine River. It's the latest operation in what aid groups call a campaign of “social cleansing” ahead of the Summer Olympics. Around 30 teenage boys and young men from West Africa were awakened by police officers and urged to pack their tents and belongings. The operation came days after police carried out a large-scale eviction at France’s biggest squatter camp. Such evictions happen every spring. But aid groups say these efforts are intensifying ahead of the Olympics. Paris police say the operation was carried out for security reasons.

WASHINGTON (AP) — U.S. health and weather officials are unveiling a new color-coded system to warn Americans about heat danger, and it will set magenta as the most dangerous level. The National Weather Service and the Centers for Disease Control and Prevention used Earth Day on Monday to explain the new online heat risk system. It combines meteorological and medical risk factors with a seven-day forecast that’s simplified and color-coded for a warming world of worsening heat waves.
