Indiana state Sen. Greg Walker said he stands by his decision to vote against a redistricting effort backed by President Donald Trump after he lost his Republican primary on Tuesday.

Trump promised retribution after the Indiana legislature voted against a redistricting effort that could have shifted two House seats in Republicans’ favor. Of the 21 Republican state senators who voted against the bill in December 2025, seven were up for reelection. All but one of the senators were voted out by Trump-enforced challengers in Tuesday’s primary. One race remains too close to call.
