In recent years, Democrats have made noise about tougher gun laws, complaining that politicians only express their "thoughts and prayers," followed by a moment of silence - but do nothing else.
"Once again a nation mourns and Congress will observe a moment of silence," said Rep. Gerry Connolly (D-VA).
"This must end," said Rep. Tim Ryan (D-OH).
But for those who do favor some type of more restrictive laws on firearms, they have been in the minority for a number of years in the Congress, even during the Obama Administration.
After the Sandy Hook shooting, efforts to push through expanded background checks on gun sales foundered, leading President Obama to instead issue a number of executive actions related to guns.
