A New York Democrat said the U.S. isn't a democracy if women can't have abortions.

"We're not even in a democracy if women can't make decisions about their own bodies," Rep. Carolyn Maloney told Fox News in front of the Supreme Court on Wednesday.

"We are speaking out against any efforts to roll back Roe v. Wade," Maloney, who chairs the House Oversight and Reform Committee, said as she exited her car to join a demonstration alongside other House Democrats.

Outside of the Supreme Court, pro-life and pro-choice groups chanted and waved signs as the court heard arguments. 

"Women's rights begin in the womb," one sign said. 

"Stop. The. Bans," read another.
