Democrats on Wednesday staged a sit-in on the floor of the House of Representatives over a lack of gun laws following the Orlando massacre.

The House was put into recess as lawmakers started sitting in. Rep. John Lewis, a Democrat from Georgia and long-time civil-rights leader, said Congress lacked courage by not addressing gun violence.

“We have lost of hundreds and thousands of people to gun violence,” Lewis said. “Mr. Speaker, what has this body done? Nothing. Not one thing.”

Here’s a few tweets from lawmakers showing the protest.

The protest was not being shown on C-Span — because the network doesn’t control the cameras.

That led one Democrat to get around the camera restriction by broadcasting the protest himself. Rep. Scott Peters of California used Twitter’s TWTR, +2.03% Periscope service to air the protest. C-Span then aired Peters’ footage. The network continued to broadcast via Periscope and Facebook Video feeds through the evening.

The bill in particular that House Democrats want to see voted on is the so-called “no fly, no buy” gun measure, which in the Senate has the backing of Sen. Susan Collins, a Maine Republican. Though that measure will have a difficult time getting enacted, it does look like the Senate will have a vote.

As Democrats continued to loudly protest, at one point singing “We Shall Overcome,” Republican leaders attempted to hold a vote Wednesday night seeking to override President Obama’s veto of a bill to nullify the “fiduciary rule,” a controversial regulation that imposes new restrictions that require financial advisers to act in the best interest of their clients.
