The Indiana Democratic Party, following a day of violence at the U.S. Capitol, has called for the resignations of Indiana lawmakers who backed objections to Electoral College votes for President-elect Joe Biden.

Those included Senator Mike Braun and four members of Indiana’s delegation to the U.S. House of Representatives.

“Braun’s rhetorical charade – which included seven flip-flops on the issue – was complicit with the domestic terrorist attack at the U.S. Capitol,” a news release from the party said. “Further, the Indiana Democratic Party is also calling for Members of Congress Jim Banks, Jim Baird, Greg Pence, and Jackie Walorski to resign for discarding their constitutional duties in favor of a vote for Trumpism and the end of the Republic.”

Braun had said earlier this month that he would vote along with about a dozen other GOP senators to reject electors from “disputed states,” and call for a commission to conduct a 10-day audit of election returns in those states, despite a lack of evidence of any widespread voter fraud having ever been committed.

He began the day Wednesday posting pictures to his Twitter account of him signing his objection to the Arizona electors and talking outside the Capitol with “supporters who came to DC from Indiana about why I will object today and support an emergency audit into irregularities in the 2020 election.”

Later that day, pro-Trump rioters stormed the Capitol as Congress convened a joint session to certify the Electoral College votes.

The chaos, which followed a nearby rally led by Trump, shutdown Congress for hours after the House and Senate chambers were evacuated when the crowds breached the building.

After the violence that left at least four people dead and dozens arrested, Braun said he had a change of heart and would withdraw his objection “ to get this ugly day behind us.”

Indiana Democratic Party chairman John Zody called the day’s events an “attempted coup” that followed “years of silence or being sycophants to Donald Trump.” Braun and the others, he said, had shown their “true colors, and it’s that they value the fringe ideology of Trumpism over protecting the U.S. Constitution and the fundamental values of the United States of America.”

“It shouldn’t take a domestic terrorist attack at the U.S. Capitol for some to speak up, and these Indiana Republican politicians have disgraced Hoosiers’ trust to uphold their constitutional duties,” Zody said in the news release. “They must resign, and if they don’t, now is the time for hardworking Indiana Democratic candidates to think about challenging them for re-election. Extraordinary times call for extraordinary actions – and that time is now.”

Indiana’s other Republican senator, Todd Young, had announced before the joint session of Congress began 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, Banks, Walorski, and Jim Baird voted against the Arizona and Pennsylvania electoral votes. Pence, a brother of Vice President Mike Pence, split his votes, supporting only the Pennsylvania results.
