Shortly before LaPierre took the stage, Trump offered a rallying cry on Twitter, calling NRA leaders "Great People and Great American Patriots".
Trump said during Friday's listening session that he thought the NRA would support raising the age to 21.
In January, President Donald Trump renewed waivers on nuclear-related sanctions for another 120 days but warned Congress and the US' European allies that they need to fix the nuclear deal or the US would withdraw from it.
Mr LaPierre used his speech to back the idea. Marco Rubio and NRA spokesperson Dana Loesch at a CNN Town Hall Wednesday night. "But the NRA, the NRA does care". "We will keep standing strong until North Korea stops threatening our country, our allies or until they abandon their nuclear and ballistic missiles once and for all".
The vehemence of his remarks might also be a sign that even the NRA is under pressure. He argued that was "more" than the Democratic Party or news organizations were doing.
Thirteen months into his presidency, Trump can still surprise.
He said the nation had become "disconnected" and that Mr Trump met and listened to people with a "spirit of humility".
Mr Pence also praised the President's meeting with the survivors and parents of shooting victims at the White House on Wednesday.
"A lot of things are happening", he said. "They want to make all of us less free". They hate the Second Amendment. And at times, particularly when he was discussing the media and the Federal Bureau of Investigation, his tone and rhetoric sounded remarkably similar to President Trump's. I don't want to tell my son, 'You're going to have to participate in an active shooter drill.' I'd much rather have a hardened school. "Gun-free zone to a maniac is let's go in and let's attack". "That's like, 'Here I am, take me'".
LaPierre didn't directly address Trump's tweets or positions in his speech.
"I don't think I'll be going up against them", he said of the politically influential group. But on Thursday, she went all in, accusing the media of "loving mass shootings" and addressing them by saying, "You love the ratings".
"The government has proven that they can not keep you safe". I'm close to them.
"Now he has to choose between his patrons and his duty as President and the country". "He can sit people down at the table on both sides of the issue and come to a compromise".
"In dealing with school safety issues, we don't expect to agree with the NRA on every single issue", Shah told reporters at the daily press briefing. "We'll get it done!" He also said he would push for an end to the sale of bump stocks, which allow rifles to shoot hundreds of rounds a minute.
"I hear a lot of quiet in this room, and I sense your anxiety", LaPierre said, turning to the political consequences of the debate.
He said existing gun laws and regulations, if executed properly, would decrease instances of mass shootings. He suggested that any further attempts at gun control would lead to mass gun confiscation and that our country would be "changed forever".
The coming struggle will match the zeal of the Florida school kids against the entrenched forces of the NRA and congressional delay.
