JTA — Alan Dershowitz, the prominent pro-Israel American attorney whose clients have included US President Donald Trump and child sex trafficker Jeffrey Epstein, announced on Monday that he was leaving the Democratic Party and registering as a Republican.

Describing himself as a “lifelong Democrat,” Dershowitz wrote in a Wall Street Journal op-ed that he had decided to “bite the bullet and register as a Republican,” citing Democratic support for an arms embargo on Israel last week and the Michigan Senate candidate Abdul el-Sayed’s anti-Israel rhetoric.

“There is no denying that the hard left, anti-Israel wing of the Democratic Party has moved from the fringe to the mainstream,” Dershowitz wrote, adding that “Republicans have their own antisemitic fringe, but for now it remains a fringe.”

The announcement formalized a political evolution for Dershowitz, who defended Trump during his first impeachment and has increasingly broken with Democrats over Israel in recent years.

In 2021, Dershowitz nominated Jared Kushner, Trump’s son-in-law, and Avi Berkowitz, Trump’s top Middle East envoy during his first administration, for the Nobel Peace Prize over their hand in shaping the Abraham Accords.

Dershowitz — who has recently faced scrutiny over his ties to Epstein, and previously denied allegations of sexual misconduct made by one of the disgraced financier’s accusers — panned the Democratic Party as the “most anti-Israel party in US history” in the op-ed.

“I believe that the Democratic Party’s hostility to Israel represents a deeper and more dangerous shift away from the center and toward a radical approach that is bad for America and the free world,” Dershowitz wrote, adding that he intended to “work hard to prevent the Democrats from gaining control of the House and Senate.”

Dershowitz’s comments are in line with Trump’s statements about Jews and the Democratic Party. The US president has repeatedly expressed amazement at how any Jews could vote for the Democrats, considering his own record on Israel.
