NRA members have branded Donald Trump’s plans for stricter gun control legislation “stupid” and a “betrayal” after the president suggested reforms on Wednesday.

In an open meeting with congressional Democrats and Republicans, Trump embraced raising the age limit on purchasing certain weapons and suggested that law enforcement should be allowed to confiscate people’s guns before going through due process in a court.

Joe Biggs, an Austin, Texas-based NRA member and chief executive of Rogue Right, a conservative news website, was among those unimpressed by the proposal.

“That’s the stupidest fucking thing I’ve ever heard in my life. Hopefully he was just having a momentary brain fart, a lapse of judgment,” Biggs said.
