"What I would like to know is, you know, what he thinks would make some progress and he would sign. And until we get that kind of guidance, we're in a holding pattern so to speak," he said.

McConnell on Tuesday describe lawmakers as in a "holding pattern" on potential gun reforms until they get a signal from Trump about what he will sign.

But the bill is considered a non-starter in the Senate, where McConnell has warned that a piece of legislation will need Trump's support in order to get a vote. The House bill has picked up no GOP cosponsors in the Senate and sparked a veto threat from the White House.

Democrats are clamoring for McConnell to bring up a universal background check bill passed by the House earlier this year with the support of eight Republican lawmakers.

"What we're asking for is very simple. ...It should be an obvious thing to do, a simple up-or-down vote on legislation, an up-or down vote on H.R. 8 let me say it again. Leader McConnell, put H.R. 8 up for a vote on the floor," Schumer added.

"Politicians offering their thoughts and prayers just doesn't cut it anymore. It's put up or shut up. Leader McConnell, Senate Republicans, what will you do?" he asked.

Senate Minority Leader(D-N.Y.) called out McConnell as he wrapped up the marathon of floor speeches, saying it was time to "put up or shut up."

Democrats are trying to build pressure on Senate Majority Leader(R-Ky.) to bring up legislation. They began speaking on the floor around 5:20 p.m.; the Senate adjourned for the day just before 10:20 p.m.

Democrats held the floor for roughly five hours on Tuesday to raise awareness about the chamber's inaction on gun legislation after a recent spate of mass shootings.

Democrats, however, are bristling over the demand from McConnell that Trump say he would support a bill before it gets a vote in the Senate, arguing it undermines the separation of powers.

"Week after week after week, we vote on nomination after nomination after nomination. We hardly ever debate. We hardly ever vote on legislation to address the needs that the American people say are the primary concerns in their minds," he added.

Democrats believe they have public momentum and polling on their side, after several recent polls have shown that most Americans support expanding background checks for gun sales.



"This is something all of us should be caring about, especially from Arizona, where my dear friend Gabby Giffords was shot," Gillibrand said during a heated speech that was audible from outside the Senate chamber.

But that support for new gun reforms hasn't carried over to the Republican-controlled Senate.

The Senate, then controlled by Democrats, previously rejected legislation in 2013 to expand background checks to all commercial sales. GOP lawmakers are wary of getting ahead of Trump on potential gun reforms, after the president signaled last year that he would support additional reforms before reversing course.The White House is currently negotiating with senators as they try to craft gun control legislation. Murphy and Sen.(D-W.Va.) both said on Tuesday that they were still waiting to find out if Trump would back an expansion of background checks for gun sales.White House Legislative Affairs Director Eric Ueland said on Tuesday that representatives from the administration would be meeting with lawmakers this week at Trump's request to try to find a bill that could clear Congress.Ueland and Attorney Generalmet on Tuesday with Sen.(R-Texas), who has warned Trump against making a deal with Democrats."The president has asked us to engage with the Hill. ... We continue today and throughout this week to talk with members on both sides of the aisle, both sides of the Capitol as we work through all these public policy challenges to see whether or not there's a path forward on a legislative package in relation to mass gun violence," he said.He added, "We got a lot of great input as you know. ... It's a collaborative two-way conversation."
