What's the story?

Rep. Seth Moulton (D-Mass.) said on Twitter Monday morning that he will not participate in a moment of silence for the victims of Sunday night's shooting in Las Vegas along with his colleagues on the House floor, because it is an "excuse for inaction."

As after #Orlando, I will NOT be joining my colleagues in a moment of silence on the House Floor that just becomes an excuse for inaction.

Now is not a moment for silence; it's a time for action.

What action is he calling for?

As he did after the 2016 Orlando Pulse nightclub shooting, Moulton is calling for Congress to pass more gun control legislation.

Thinking of everyone in #LasVegas, and praying Congress will have the courage to do more than stand in silence to commemorate them.

Why does it matter?

Sunday's mass shooting at a Las Vegas country music festival has fueled the ongoing controversy over gun laws, with gun control advocates insisting the country needs more gun laws, and Second Amendment advocates calling for citizens to have the right to protect themselves from criminals.

Former Democratic presidential nominee Hillary Clinton said Americans should "put politics aside" and "stand up to the NRA" following the deadly mass shooting.
