Obama denounces US Senate, says shootings requires more than a moment of silence

Washington: President Barack Obama has denounced the Senate's failure to pass gun control measures in the aftermath of the mass shooting in Orlando, Florida.

Obama on Twitter said that the Senate failed the American people and that gun violence requires more than a moment of silence.

The White House has said previously that tweets from his account are from Obama himself. White House spokesman Josh Earnest says the vote is a "a shameful display of cowardice". He said on Tuesday that the Republican-led chamber's blocking of four gun control proposals on Tuesday does nothing to keep extremists from acquiring guns.

Earnest said lawmakers lament gun violence but "don't do anything about it." He said that while no bill can prevent all gun violence, "why wouldn't we do more?"
