The US Democrat lawmakers has held a "sit-in" in support of controlling  sales of arms. About 60 congressmen blocked the rostrum of the House of Representatives and did not allow the majority of Republicans to pass.

Every lawmaker from Democrats gave a speech in favor of restrictions on arms sales. They said they would not move until the spokesman Paul Ryan holds voting on measures of controlling sales of arms.

They did not allow Ryan to hold a procedural vote on another matter. The US President Barack Obama and the Secretary of State Hillary Clinton supported the protest in their Twitter. On Monday the Senate failed to pass 4 bills aimed at controlling the sale of weapons in the country.
