美民主党众议员静坐，要求表决控枪议案

Rallying around their cry, "No bill, no break," House Democrats pressed on early Thursday in their sit-in calling for a vote on gun control legislation before leaving on their Independence Day break.

Led by civil rights icon John Lewis of Georgia, Democrats pledged to remain in the House in a “sit-in” until legislation is brought forward.

Republicans initially responded with gavel-banging and demanding order on the floor. When Democrats refused to disperse, Republicans recessed the chamber and turned off the microphones. Although lights continued to shine, proceedings ceased to be televised, because video is fed from the chamber only when it is in session.

Democrats responded by launching their own broadcasts, using the mobile application Periscope on their cellular phones. A non-profit U.S. cable outfit that covers congressional proceedings (C-Span) began broadcasting the Periscope feeds.

乔治亚州民主党众议员约翰·路易斯是美国民权运动的象征性人物。在他的带领下，民主党议员们誓言要在国会一直进行静坐下去，直到控枪议案付诸表决。

共和党议员最初还想敲议事锤来维持秩序，但民主党议员拒绝停止静坐。共和党人于是宣布休会，并关了麦克风，虽然大厅里灯还亮着，但是因为处于休会状态，所以大厅里的情况电视并没有转播。

民主党议员用一款名叫潜望镜的手机应用，把实况录像送上网，专门播报国会议事动态的非营利有线电视台C-Span随即开始播放潜望镜上的内容。
