Schwarzman, a billionaire and lifelong moderate Republican, was one of Trump's most visible business supporters when he was in the White House.

• But ahead of this year's GOP primaries, Schwarzman called for "a new generation of leaders." Schwarzman wound up not backing a primary candidate.

Axios is told Schwarzman's concern about rising antisemitism sped his decision to re-embrace Trump, along with concerns about President Biden's policies.

• "The dramatic rise of antisemitism has led me to focus on the consequences of upcoming elections with greater urgency," he says in a statement to Axios.
