Democratic lawmakers ground the U.S. House to a halt Wednesday, staging a sit-in to demand a vote on gun control legislation. Scores of House lawmakers took to the House floor Wednesday morning and have refused to let Republicans take back control. They have taken turns talking about gun violence, said they wouldn't leave until House Speaker Paul Ryan, R-Wis., allowed a vote on measures to curb it, and chanted over and over "No bill, no break!" The House is scheduled to adjourn on Friday and be out of session until July 5. Most of the House demonstration, unlike last week's filibuster in the Senate that led to the votes Monday, was not broadcast on C-SPAN. The network carries feeds from cameras belonging to the House, which controls what is broadcast.
