During a “Day without women” protest on the steps of the U.S. Capitol, Nancy Pelosi and other Democrat members of Congress railed on Donald Trump and Republicans.

But during her remarks, Pelosi hailed Jeannette Rankin, the first woman to serve in Congress.

“This is a day that is very interesting because we are observing the 100th anniversary of the first woman elected to Congress, Jeannette Rankin of Montana,” Pelosi said to cheers.

“It’s pretty exciting. Women in America did not have the right to vote yet. In Montana they did and they sent a woman to Congress and she made a difference here,” she said.

Little did her colleagues know they were cheering for a Republican.

According to House.gov, Rankin was “one of the few suffragists elected to Congress” and the “committed pacifist” served two terms, each at the outset of both World Wars.
