The recent mass shooting in Orlando prompted the senators from each party to introduce the measures aimed at strengthening background checks and prevented suspected terrorists from obtaining weapons.
But looming election and the disputes over the effectiveness of each party's ideas once again proved to be the nemesis of the measure.
Sen. Chris Murphy, a Connecticut Democrat who sponsored one of the failed measures expanding background checks, looked angry after his provision was defeated. "I'm mortified by today's vote but I'm not surprised by it," Murphy said Monday evening. "The NRA has a vice-like grip on this place."
"I don't think democracy allows for this Congress to be do out of step with the American public for long," he said.
Just before the votes, Murphy had told reporters for The Washington Post: "We've got to make this clear, constant case that Republicans have decided to sell weapons to ISIS."
Outspoken liberal Sen. Elizabeth Warren also echoed similar feelings after the votes.
On Monday, the measures went down in succession on largely party line votes. The 60-vote threshold needed for passage prevented even Republicans from pushing through their favored measures.
The Senate fist rejected a Republican proposal to update the background check system for gun purchases. The proposal was sponsored by Iowa GOP Sen. Chuck Grassley and it failed to get the 60 votes for passage.
