WASHINGTON D.C. — Senator Cynthia Lummis joined six other Senate Republicans in opposing the certification of Pennysylvania’s election results last night after a mob stormed the U.S. Capitol.

The House and Senate resumed a debate over the legitimacy of the presidential election hours after a pro-Trump mob stormed the U.S. Capitol and drove lawmakers from their chambers. The Senate and House rejected objections to throw out Georgia and Pennsylvania’s electoral votes for Biden. Republicans also objected to Arizona, Nevada, and Michigan’s electoral votes, but the motions failed before they reached debate.

Lummis’ first vote as a United States senator was to vote to certify Arizona’s election results. Hours later, she joined six other Senate Republicans in opposition of Pennsylvania’s vote, saying in a statement, “I have serious concerns about election integrity, especially in Pennsylvania, and expressed some of them in a written statement to the Senate. But today’s sickening, un-American attack on the U.S. Capitol overshadowed that debate.”

Just days prior, Lummis had been amongst a group of 11 republicans who were challenging the 2020 election results. “I’m joining a number of colleagues to follow the steps laid out in the 12th Amendment + the process established in the Electoral Count Act of 1887 to protect the vote for all Americans & begin work to restore the shaken confidence of many US voters,” she tweeted on Jan. 2.

At 3:32 a.m., Vice President Pence officially affirmed the election results of President-elect Joe Biden’s win, nearly 15 hours after the joint session began.
