Last week, he directed his administration to regulate bump stocks, the gun accessory used to simulate automatic fire in the 2017 Las Vegas attack.
He called for comprehensive gun control legislation that would expand background checks to weapons purchased at gun shows and on the Internet, keep guns from mentally ill people, secure schools and restrict gun sales from some young adults.
Trump also heard from a Colorado state lawmaker who survived the 1999 shooting rampage at a high school there that left 13 dead; two founders of a gun control organization formed in the wake of a 2012 shooting at a CT elementary school that killed 26 people; and a man who confronted the shooter a year ago at a Texas church where 26 were left dead.
Though he did not mention increasing the minimum age for rifle purchases, he wants to toughen the Cornyn bill with stricter background checks, a change the NRA has opposed.
"You know why? Because you're afraid of the NRA", Trump responded before pointing and laughing. Pat Toomey, R-Pa., and Joe Manchin, D-W.Va., has found new momentum since it was first introduced after the 2012 shooting at Sandy Hook Elementary School in CT that left 20 children dead.
As the meeting went on Trump again seemed to suggest the government could ignore due process rights when confiscating weapons.
Under President Barack Obama, people rushed to buy guns they feared would be outlawed.
"If our attitude is, 'I want everything on my list or nothing, ' we're going to end up with nothing", he warned. Joe Manchin of West Virginia wrote bipartisan legislation on the subject and Trump appears to consider it the main bill Congress should build on. "We should be focusing on making sure that citizens who should not get guns in the first place don't get those guns". "I'm glad that it, like, brought us together. instead of dragging us apart", said Marjory Stoneman Douglas High School student Destiny Briceno. Democrats are calling for universal gun background checks, while Republicans support more modest efforts to beef up the national background check system. He says gun-free zones around schools are "proven targets of killers".
Officials at the powerful gun group were taken aback by Mr Trump's comments and immediately ramped up their lobbying against measures that they have long said would damage the Second Amendment and do little to protect people against gun violence. "I just don't think you're going to get it approved, you're not going to get concealed carry approved", Trump said.
"WHAT??" wrote Fox host Laura Ingraham in response to Trump's drive for lawmakers to raise the age limit and accusation that they are afraid of the NRA.
On Thursday, Trump tweeted, "many ideas, some good and some not so good, emerged from our bipartisan meeting on school safety yesterday at the White House".
Jennifer Baker, an NRA spokeswoman, denied that her organization made such overtures to Congress, and said the NRA's main concern was not gun sales but rather defending gun rights. The bill would broaden background checks and Toomey says "the president really could make the difference".
Ever the marketer, Trump suggested that the leading bill adjusting the National Instant Criminal Background Check System - now known as "Fix NICS" - could use a new name. "If you add concealed carry to this you'll never get it passed", he pushed.
Trump is tweeting that "Background Checks a big part of conversation".
Afterward, Toomey and Manchin said in a joint statement that the meeting was "very encouraging", and that "per the president's instruction, Congress shouldn't wait" on sending Trump gun legislation. "Respect 2nd Amendment!" and the constitutional right to bear arms, the president said.
