INDIANAPOLIS (AP) — Republican Indiana Sen. Mike Braun dropped his objections to Joe Biden’s Electoral College votes after a mob of President Donald Trump supporters stormed the Capitol building.

Braun said that Wednesday’s violence “changed things drastically.”

Braun had announced over the weekend that he would join about a dozen Republican senators and dozens more House Republicans to challenge the Electoral College votes from some states Biden won in November’s election.

“Though I will continue to push for a thorough investigation into the election irregularities many Hoosiers are concerned with as my objection was intended, I have withdrawn that objection and will vote to get this ugly day behind us,” Braun said in a Twitter statement.

Indiana’s other Republican senator, Todd Young, had announced before the joint session of Congress began Wednesday that he wouldn’t support the objections to Biden’s electoral votes, saying he would “uphold my constitutional duty and certify the will of the states as presented.”

Among Indiana’s House members, Republican Reps. Jim Banks, Jackie Walorski and Jim Baird voted against the Arizona and Pennsylvania electoral votes. Rep. Greg Pence, a brother of Vice President Mike Pence, split his votes, supporting only the Pennsylvania results.
