Only a few weeks after a gunman shot and killed 49 people in an Orlando nightclub, the battle over gun control is still raging in Congress.
And there could be some movement next week: in an unexpected move, House Speaker Paul Ryan told Republicans on a conference call Thursday that the House will vote on a yet-to-be-announced gun control proposal when members return from the July 4th recess.
With a new round of discussions about stricter gun laws seemingly coming up after every major mass shooting--more than 100 measures have been proposed, and failed, since 2011--it's sometimes tough to keep track of who's proposing what and what those new measures would actually do.
Here's a look from CBS News at where things stand:
What's being voted on next week?
The legislation itself hasn't been introduced or announced yet, so we don't know exactly what it will look like. That said, Democrats expect it to be similar to legislation proposed earlier this month in the Senate by John Cornyn (R-Texas).
Cornyn's proposal, which was supported by the National Rifle Association, would allow the attorney general to prevent people on terror watch lists from buying guns--but only after proving probable cause, which would need to be done before a judge within 72 hours.
That proposal doesn't go far enough for Democrats, who opposed it in the Senate and say the standards are too high and the timeframe is too short to effectively stop potential terrorists from acquiring guns.
"House Democrats will keep up our efforts to push for the Majority to allow a vote on gun violence legislation, but bringing up a bill authored by the NRA just isn't going to cut it," said Drew Hamill, a spokesman for Minority Leader Nancy Pelosi.
Next week's votes will be part of a bigger-picture package focused on terrorism, a source told CBS News. One thing we do know will be included in the votes is a mental health reform bill from Rep. Tim Murphy (R-Pennsylvania), since terrorism and mental illness have both been deemed as causes for recent mass shootings.
What's been proposed so far?
The Senate has voted on several different gun control provisions, including Cornyn's. Those votes came shortly after Democrats, led by Sen. Chris Murphy (D-Connecticut), led a nearly 15-hour filibuster on the Senate floor to draw attention to the gun control issue.
When it comes to the "no fly, no buy" legislation, there have been several different proposals. Democrats' initial proposal, sponsored by Sen. Dianne Feinstein (D-California), would have banned people in the FBI's Terrorist Screening Database, including the no-fly list, from purchasing a gun in the U.S.--a measure she said would have caught Orlando shooter Omar Mateen.
The difference between Feinstein's proposal and Cornyn's, both of which failed earlier this month, is that Republicans want to require more proof from government officials that an individual is likely to commit terrorism.
Collins' bipartisan proposal would prohibit people on the no-fly list and the government's selectee list, used for extra screening at airports, from purchasing guns. However, U.S. citizens and green-card holders would be able to appeal if they're blocked from buying a firearm. That proposal passed a procedural vote in the Senate, but is unlikely to get the 60 votes it would need to advance further.
The other two measures that failed in the Senate this month both dealt with background checks: one, from Sen. Chuck Grassley (R-Iowa), would have increased resources for the National Instant Criminal Background Check System. Another, from Murphy, would have expanded background checks for private gun sales.
What's happening in the House?
This will be the first major vote in the House on gun measures during the most recent push for legislation--but it's not for lack of trying on Democrats' part.
Dozens of Democratic lawmakers staged a nearly 26-hour sit-in on the House floor last week, staying overnight to demand action over gun control. The protest, led by Rep. John Lewis (D-Georgia),
At the time, Ryan said a vote on gun measures wouldn't be happening any time soon.
"We want to make sure something like this doesn't happen again," Ryan said at a press conference in mid-June. "We also want to make sure that we're not infringing upon legitimate constitutional rights."
Republicans are also reportedly mulling some sort of formal response to the Democrats' sit-in, with a source telling CBS News the GOP will "take any action we deem necessary."
What does the public think of stricter gun control measures?
Polling finds most Americans are in favor of the "no fly, no buy" legislation. A Quinnipiac University poll released Thursday found that a full 86 percent of registered voters back legislation aimed at barring people on terror watch lists from purchasing guns, compared with just 12 percent who oppose it. Even among voters who live in households with a gun, the proposal gets overwhelming support: 83 percent back something like "no fly, no buy," compared with 14 percent who don't.
That support for stricter laws extends beyond just "no fly, no buy" legislation: 93 percent of registered voters also favor requiring universal background checks for all gun buyers. Just six percent do not favor universal background checks.
Another survey from CBS News, conducted shortly after the Orlando attack, found similar numbers: 89 percent of those surveyed support universal background checks. And asked how they feel about the prospect of an assault weapons ban, found that a majority of Americans (57 percent) favor such a ban.
The survey from Quinnipiac also found that almost two-thirds of voters (64 percent) agree that "it's possible to make new gun laws without interfering" with Second Amendment gun rights.
