Indiana Gov. Mike Braun said that he will seek to oust members of the Indiana Senate who voted against a bill to redraw the state’s congressional district maps ahead of the 2026 midterm elections.

Braun, who took office this year after serving as the junior U.S. senator from Indiana, wrote on social media Thursday that the senators in question had “partnered with Democrats ... to reject the leadership of President [Donald] Trump.” He said that he would be “working with the President to challenge these people who do not represent the best interests of Hoosiers.”

The next elections to the Indiana Senate will occur on Nov. 2, 2026, where 25 of the body’s 50 seats will be subject to election. Most of the incumbent senators seeking reelection are Republicans, and the party currently holds a two-thirds majority in the body.

The Indiana Senate rejected the bill, HB 1032, by a vote of 19 yeas to 31 nays. More Republicans voted against the bill than for it, with 21 of them joining the body’s 10 Democrats to defeat it. The Indiana House of Representatives, on Dec. 5, had passed the bill by a vote of 57 to 41.

In a long Truth Social post, Trump threatened the senators who voted no with primary challenges.

“Anybody that votes against Redistricting, and the SUCCESS of the Republican Party in D.C., will be, I am sure, met with a MAGA Primary in the Spring,” Trump wrote. “[Indiana Senate President pro tempore] Rod Bray and his friends won’t be in Politics for long, and I will do everything within my power to make sure that they will not hurt the Republican Party, and our Country, again. One of my favorite States, Indiana, will be the only State in the Union to turn the Republican Party down!”

Vice President JD Vance also weighed in.

“Rod Bray, the Senate leader in Indiana, has consistently told us he wouldn’t fight redistricting while simultaneously whipping his members against it. That level of dishonesty cannot be rewarded,” wrote Vance on social media.

The Republican senators who voted no cited the highly partisan nature of redistricting and forecast that the effort would be undermined by legal challenges.

Bray defended his actions in a statement after the vote.

“Indiana Senate Republicans want to see a Republican majority in Congress at the midterms. The issue before us today was how to get there, and many of my caucus members don’t think redrawing our congressional map midcycle is a guaranteed way for Indiana—or for our country—to achieve that outcome,” wrote Bray in his statement.

“We support President Trump, and we are with him on many important issues,” he added.

“Further, we are grateful for the way President Trump speaks about our great nation full of good people.”
