Ken Griffin backs GOP Senate

Republicans' fight to preserve their Senate majority is drawing fresh money from one of the party's most prominent donors. Ken Griffin is giving $10 million to the main Senate super PAC and additional funding to candidate-specific efforts in competitive contests.

Highlights

  • Ken Griffin donated $10 million to the GOP Senate super PAC as Republicans aim to defend their majority.
  • Griffin contributed $2.5 million to a PAC supporting Alaska Senator Dan Sullivan, who faces a strong challenge from Democrat Mary Peltola.
  • The allocations underscore major donors' focus on pivotal Senate races determining Republican control.

Funding targets key Senate contests

As reported by Bloomberg, citing Federal Election Commission filings, Griffin directed $10 million to the Republican Party's main Senate super political action committee as the GOP works to defend its chamber majority.

He also contributed $2.5 million to a super political action committee supporting Alaska Senator Dan Sullivan, an incumbent Republican facing a closely watched challenge in the state.

Alaska race underscores majority stakes

Sullivan is running against former Representative Mary Peltola, a Democrat who has previously shown she can win in Alaska despite the state's long record of backing Republican presidential candidates since 1964.

The donations highlight how major financiers are concentrating resources on races seen as critical to determining whether Republicans can keep control of the Senate.
