WASHINGTON (AP) — President Joe Biden is staying mum about student protests and police crackdowns as Republicans try to turn campus unrest over the war in Gaza into a campaign cudgel against Democrats.

Tension at colleges and universities has been building for days as some demonstrators refuse to remove encampments and administrators turn to law enforcement to clear them by force, leading to clashes that have seized attention from politicians and the media.

But Biden’s last public comment came more than a week ago, when he condemned “antisemitic protests” and “those who don’t understand what’s going on with the Palestinians.”

The White House, which has been peppered with questions by reporters, has gone only slightly further than the president. On Wednesday, press secretary Karine Jean-Pierre said Biden is “monitoring the situation closely,” and she said some demonstrations had stepped over a line that separated free speech from unlawful behavior.
