Senate Minority Leader Chuck Schumer (D-NY) has accused President Donald Trump of “weaponizing antisemitism” over the administration’s decision to cut federal funding to universities who fail to protect Jewish students.

“Stop disgracefully weaponizing antisemitism to attack universities,” wrote Schumer in a social media post on Thursday timed with Holocaust Remembrance Day. “He’s failing to address the real problem of antisemitism—instead using this crisis as a pretext to attack those who disagree.”

Schumer’s criticism came alongside four fellow Jewish Democratic senators: Richard Blumenthal (D-CT) of Connecticut, Jacky Rosen (D-NV) of Nevada, Adam Schiff (D-CA) of California, and Brian Schatz (D-HI) of Hawaii, who joined in a formal letter on Thursday accusing Trump of exploiting antisemitism concerns for political gain.

In their letter, the senators expressed concern over what they termed Trump’s “broad and extralegal attacks against universities and higher education institutions as well as members of their communities.” Additionally, they alleged that the president’s actions “seem to go far beyond combating antisemitism, using what is a real crisis as a pretext to attack people and institutions who do not agree with you,” and accused him of “undermining or even destroying these vital institutions while hiding behind claims of tackling antisemitism as a guise.”

No love has been lost over the years between Schumer and Trump, with the latter often referring to America’s highest ranking Jewish official as a “Palestinian” who supports Hamas.
