Sen. Bill Cassidy (R-LA) has put wind in the sails of Todd Blanche’s nomination as attorney general, announcing in a Friday floor speech that he will cast the decisive “yes” vote on the Senate floor.

The decision amounts to a major victory for President Donald Trump from an unlikely ally. Cassidy, who voted to convict the president in his 2021 impeachment trial, recently lost his primary to a Trump-backed challenger and has since become a less reliable Republican vote.
