In an extraordinary act of political retaliation, Tennessee Republicans on Thursday expelled two Democratic lawmakers from the state Legislature for their role in a protest calling for more gun control in the aftermath of a deadly school shooting in Nashville. A third Democrat was narrowly spared by a one–vote margin.

The split votes drew accusations of racism, with lawmakers ousting Reps. Justin Jones and Justin Pearson, who are both Black, while Rep. Gloria Johnson, who is white, survived the vote on her expulsion. Republican leadership denied that race was a factor, however.

Banishment is a move the chamber has used only a handful times since the Civil War. Most state legislatures have the power to expel members, but it is generally reserved as a punishment for lawmakers accused of serious misconduct, not used as a weapon against political opponents.

Jones, Pearson and Johnson joined in protesting last week as hundreds of demonstrators packed the Capitol to call for passage of gun–control measures. As the protesters filled galleries, the three approached the front of the House chamber with a bullhorn and participated in a chant.

The protest unfolded days after the shooting at the Covenant School, a private Christian school where six people were killed, including three children.

“We are losing our democracy. This is not normal. This is not OK,” Pearson told reporters Thursday. The three “broke a House rule because we’re fighting for kids who are dying from gun violence and people in our communities who want to see an end to the proliferation of weaponry in our communities.”

Johnson, a retired teacher, said her concern about school shootings was personal, recalling a day in 2008 when students came running toward her out of a cafeteria because a student had just been shot and killed.

“The trauma on those faces, you will never, ever forget. I don’t want to forget it,” she said.

Thousands of people flocked to the Capitol to support Jones, Pearson and Johnson on Thursday, cheering and chanting outside the House chamber loudly enough to drown out the proceedings.

The trio held hands as they walked onto the floor, and Pearson raised a fist during the Pledge of Allegiance.

Offered a chance to defend himself before the vote, Jones said the GOP responded to the shooting with a different kind of attack.

“We called for you all to ban assault weapons, and you respond with an assault on democracy,” he said.

Jones vowed that even if expelled, he would continue pressing for action on guns.

“I’ll be out there with the people every week, demanding that you act,” he said.

Republican Rep. Gino Bulso said the three Democratic representatives “effectively conducted a mutiny.”
