Three Democratic senators will join Sandy Hook parents and other family members of victims of gun violence Thursday morning on Capitol Hill to push lawmakers to swiftly pass a bipartisan gun control bill waiting in the Senate.

The senators -- Chuck Schumer of New York and Richard Blumenthal and Chris Murphy of Connecticut -- will join with Newtown parents and a survivor from the Aurora shooting in Colorado around 10:30 a.m. to talk about the bipartisan compromise brokered Wednesday that could revive the momentum lost months after these mass shootings spurred national debate.

Sens. Joe Manchin, D-W.Va., and Pat Toomey, R-Pa., revealed a compromise Wednesday that would expand federal background checks to gun shows and online sales. That bill, which will be an amendment to the large Senate gun control legislation, will not affect personal transactions.

The Sandy Hook parents are currently on Capitol Hill reading the names of more than 3,000 Americans who died because of gun violence since 20 of their children and six educators were murdered in December.

They are hoping to make an emotional appeal to lawmakers who are threatening to filibuster the 2013 gun control bill that would also boost funding for safer schools and toughen laws on gun traffickers.

The Senate is scheduled to vote Thursday to move the measure forward for debate.

An aide for Schumer told the International Business Times that the senator will return an unsurprising "yes" vote and that the others joining him this morning are expected to follow suit.
