Casey, long a staunch supporter of Israel, has criticized acts of antisemitism on campuses and pointed to legislation he sponsored as a way to make sure the Education Department takes action.

“Students of course have the right to peacefully protest, but when it crosses the line either into violence or discrimination, then we have an obligation to step in and stop that conduct,” Casey said Thursday as he urged colleagues to pass his bill.

Democratic Sen. Jacky Rosen of Nevada, who is Jewish and facing reelection, said she was “horrified” by displays of antisemitism on campuses and, like Casey, called for the department to hold schools accountable.

In California, U.S. Rep Adam Schiff, the Democratic nominee for an open Senate seat, took aim at the Columbia demonstration and said “antisemitic and hateful rhetoric is being loudly and proudly displayed.” Accused by Garvey of being “incredibly silent” on the protests, Schiff, who is Jewish, voted for a House bill similar to Casey’s and released a statement that condemned violence and the “explicit, repeated targeting and intimidation of Jewish students.”

Republicans elsewhere contended statements by Democrats were equivocating and inadequate.

Republicans called out Sen. Sherrod Brown, D-Ohio, after he told an Axios reporter last week that he was “not going to talk about the politics of that. People always have the right to speak out and should.”

His Republican opponent, Bernie Moreno, charged that Brown had “wholeheartedly endorsed these vile and violent antisemitic demonstrations.”

Later, at a news conference, Brown gave more expansive comments. “Students want to make their voices heard, they need to do it in a way that’s nonviolent, they need to do it in a way that doesn’t spew hatred, and laws need to be enforced,” he said.

In Michigan, which has a relatively significant Muslim population, Biden’s handling of the war is expected to factor heavily into the presidential and Senate races.

Rogers, a favorite for the GOP nomination, thanked New York City police for confronting protesters and “standing up to protect Jewish students at Columbia from the visceral hatred we’ve witnessed from Hamas sympathizers on their campus.”

Republicans argued that U.S. Rep. Elissa Slotkin, the front-runner for the Democratic nominationfor Senate, had not spoken out strongly against protests at Columbia, her alma mater, and that she took five days after they began to say anything at all.

Slotkin, who is Jewish, said in an April 22 statement — the most recent wave of demonstrations began at Columbia on April 17 — that “the use of intimidation, antisemitic signs or slogans, or harassment, is unacceptable.”

It was, she suggested, a complicated topic.

“I would rather be thoughtful and take more time than have a knee-jerk answer for any issue,” Slotkin said in an interview. “But especially this one.”
