Pearson and Jones, along with Democrat Reps. Gloria Johnson, egged on protesters and stormed the state House floor to call on their colleagues to take action against gun violence last month.

As a consequence of their actions, both Pearson and Jones were expelled from the House by Republicans.

"We do not believe that breaking decorum is alone sufficient cause for employing the most draconian of consequences to duly-elected lawmakers," Schumer and Warnock wrote in their letter to Garland. 

The letter continues, "This is un-democratic, un-American, and unacceptable, and the U.S. Department of Justice should investigate whether it was also unlawful or unconstitutional."
