Lawyers affiliated with an anti-Israel office facing a Senate investigation poured tens of thousands of dollars into Democratic campaign coffers, records show.

Rutgers Law School’s Center for Security, Race and Rights is under the spotlight due to federal judicial nominee Adeel Mangi’s previous role advising the New Jersey-based group, which received a request for funding records in February from Senate Judiciary Committee Republicans looking into its promotion of “terrorist-sympathizers.” The Rutgers-housed center’s director Sahar Aziz, who was awarded a paid fellowship from the philanthropy network of left-wing billionaire George Soros, and numerous academics linked to the center have cut checks over the years to congressional Democrats and presidential campaigns, according to Federal Election Commission filings.
