Two Democratic lawmakers are taking the movement to remove Confederate memorials to Capitol Hill.

Sen. Cory Booker, N.J., and Rep. Barbara Lee, Calif., introduced House and Senate versions of the Confederate Monument Removal Act, which would mandate the removal of all statues of those who voluntarily served the Confederate States of America from the National Statuary Hall Collection within 120 days.

There are currently 12 Confederate leaders, including Gen. Robert E. Lee and President Jefferson Davis, in the National Statuary Hall Collection.

“The National Statuary Hall Collection is intended to honor American patriots who served, sacrificed, or made tremendous contributions to our nation,” Booker said.

“Those who committed treason against the United States of America and led our nation into its most painful and bloody war are not patriots and should not be afforded such a rare honor in this sacred space.”

Activists around the country have been protesting Confederate memorials and pushing measures to call for their removal.

Those efforts hit a tragic crescendo last month in Charlottesville, when a white supremacist plowed his car into a crowd, killing one counterprotester at a rally organized by those wanting to preserve the statues.

House Minority Leader Nancy Pelosi, D-Calif., and other Democrats called for the immediate removal of the statues in the Capitol after the Charlottesville attack.

But this is the first piece of bicameral legislation aimed at doing so, according to a spokesman for Lee.

Lee called the memorials “hateful symbols” unfit for the U.S. Capitol.
