Democratic presidential candidate Hillary Clinton tweeted her support for a sit-in by Democratic members in the US House of Representatives, ABC News reported on Thursday.

On Monday, the Senate failed to advance four gun measures, including one that would have prohibited gun sales to people on a broad range of government watch lists.

Senators from both parties now are pushing for a compromise.

Senate Majority Leader Mitch McConnell said he would schedule a vote on the measure by fellow Republican senator Susan Collins that would prevent about 109,000 people on "no-fly" and other surveillance lists from purchasing guns.

They were holding private talks on the bill and Collins said it could be voted upon this week.

She said one of the issues being negotiated was the question of protecting the constitutional rights of gun buyers.

The powerful National Rifle Association (NRA) said it opposed the compromise bill and called it unconstitutional.
