Francys Johnson, the former head of the Georgia NAACP who is now affiliated with the New Georgia Project, was also among those taken into custody.
The demonstration began a couple of hours earlier in front of the U.S. Supreme Court when Johnson and several other speakers implored Congress to reform the filibuster in hopes of making it easier to pass two federal voting laws.
One, titled the For the People Act, is a wide-ranging proposal that would implement new standards for early voting and automatic voter registration, campaign finance transparency rules, limits to partisan gerrymandering and ethics guidelines for federal lawmakers. The second bill, which is named after Georgia Congressman John Lewis, would reinstate federal review of voting law changes in states with a history of discriminatory practices.
Johnson is the second U.S. House member in a week to be arrested after participating in a protest backing this legislation. On July 16, Ohio Rep. Joyce Beatty was taken into custody after leading a protest inside the Hart Office Building.
After being processed by U.S. Capitol Police, the group arrested Thursday expected to post bail and be released.
