The U.S. Senate rejected four gun control measures -- two sponsored by Republicans, two by Democrats -- on Monday, ending another attempt to expand background checks and stop people on terror watch lists from getting guns.

Democrats forced the issue last week after a 15-hour filibuster in the Senate, but there were dim prospects that any of the amendments would pass as Democrats saw Republican compromises as little effort and refused to budge from their positions.

  • Senate voted against cloture on 4 gun measures
  • Votes come a little more than a week after terror attack at Pulse nightclub

The Democratic filibuster was in response to the Pulse nightclub attack in Orlando, and was led by Sen. Chris Murphy of Connecticut, who also invoked the victims of the 2012 massacre at Sandy Hook Elementary School in his home state.

Senators John Cornyn and Dianne Feinstein did attempt to find a compromise on the amendment to ban terror suspects from buying guns, but in the end both parties put forth their own versions of the amendments, which fell largely on party lines.

The measures were all proposed amendments to an appropriations bill covering the departments of Commerce and Justice. All of the amendments had to pass a cloture vote in order to pass for a final vote on the Senate. Each amendment needed 60 votes to pass.

Even if any of the amendments made it through the Senate, they had little chance of passing the U.S. House.

The amendments

Amendment by Democratic Sen. Chris Murphy of Connecticut that would require background checks for all gun sales (including private sales and sales online) and improve information in the National Instant Criminal Background Check System. Failed to pass cloture, 44-56. See how the Senators voted

Amendment by Judiciary Committee Chairman Charles Grassley, R-Iowa, that would boost funds for the National Instant Criminal Background Check System and ensure that the correct records are uploaded into the system in a timely manner. Would also clarify language surrounding mental health issues that would disqualify someone from buying a gun. Failed to pass cloture, 53-47. See how the Senators voted

Amendment by Democratic Sen. Dianne Feinstein of California that would let the government bar sales of guns and explosives to people it suspects of being terrorists. Would have affected anyone on the terrorist watch list or anyone who had been investigated in connection with terrorism over the past five years. Feinstein offered a similar 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. Failed to pass cloture, 47-53. See how the Senators voted

Amendment by Republican Sen. John Cornyn of Texas that would allow the government to delay a gun sale to a suspected terrorist for 72 hours, but require prosecutors to go to court to show probable cause to block the sale permanently. Failed to pass cloture, 53-47. See how the Senators voted
