Senate Democrats ended a nearly 15-hour filibuster early Thursday after Republican Party leaders reportedly agreed to allow votes on two proposed gun control measures.
Sen. Chris Murphy, a Democrat from Connecticut, said that a compromise had been reached. Votes would be held on whether to ban people on the government's terrorist watch list from obtaining gun licenses and whether to expand background checks to gun shows and internet sales, he added.
"We did not have that commitment when we started today," Murphy said.
The nonstop series of speeches stretched 14 hours and 50 minutes. It followed the shooting massacre at a gay nightclub in Orlando.\

"I've had enough. I've had enough of the ongoing slaughter of innocents, and I've had enough of inaction in this body," Murphy said during the filibuster which he launched at around 11:21 a.m. Wednesday. He vowed to remain on the Senate floor "until we get some signal, some sign that we can come together."
Forty senators joined Murphy, according to C-SPAN2.
By Senate rules, Murphy had to stand at his desk to maintain control of the floor. When asked by another senator how he was feeling just before 7:30 p.m., Murphy said rehabilitation from a back injury in his 20s had helped him build up endurance.
Murphy said he wants Congress to enact tighter restrictions to prevent those with serious criminal histories; those deemed mentally incompetent; and those on terrorism watch lists from obtaining firearms.
He began the filibuster three days after a gunman who had been investigated by the FBI — the agency says it found no credible threat — opened fire at the Pulsenightclub in Orlando, Florida, killing 49 people in the worst mass shooting in modern American history.
The weapons carried by the gunman, Omar Mateen, were legally purchased. He bought the Sig Sauer MCX semi-automatic rifle and a handgun in the week before the massacre, officials said.
"What unites all of these shootings, from Littleton to Aurora, to Newtown, to Blacksburg to Orlando, is that the weapon of choice in every case is a gun — often a very powerful gun, an AR-15 or an AR-15-style gun that was designed for the military, for law enforcement to kill as many people as quickly as possible," Murphy said.
Murphy's state of Connecticut saw the mass killing of 20 school children and six staffers at Sandy Hook Elementary School in Newtown on Dec. 14, 2012.
He closed the filibuster by saying: "I have been furious since those days following Sandy Hook. I have been so angry that this Congress has mustered absolutely no response to mass shooting after mass shooting, in city after city that is plagued by gun violence."
Sunday's shooting has revived calls from Democrats pushing for gun control legislation.
The National Rifle Association is fiercely opposed to what its leaders called a series of anti-gun bills and amendments, and warned its members Wednesday that the measures are a threat to the right to own firearms.
Presumptive Republican presidential nominee Donald Trump, who has been endorsed by the NRA, told a crowd in Georgia: "I'm going to save your Second Amendment."
It's been nearly a decade since Congress made any significant changes to federal gun laws. In April 2007, Congress passed a law to strengthen the instant background check system after a gunman at Virginia Tech was able to purchase his weapons because his mental health history was not in the instant background check database. Thirty-two people died in the shooting.
Murphy said Senate leadership agreed to allow a vote on legislation from Sen. Dianne Feinstein, D-Calif., that would let the government bar sales of guns and explosives to people it suspects of being terrorists.
Feinstein offered the amendment in December, a day after an extremist couple killed 14 people in San Bernardino, California, but the Republican-run Senate rejected the proposal on a near party-line vote. He said the compromise also will allow a vote on an amendment to expand background checks.
Sen. Bob Casey, who represents Pennsylvania, spoke at around 12:30 a.m. Thursday, called on legislators to allow the votes.
"At least put your hand up for a vote that will begin, just begin the long journey to rectify a substantial national problem that takes 33,000 people every year," Casey said. "All we're asking for is a start."
The Senate is due back in session at 10 a.m. ET on Thursday.
