WASHINGTON – Donald Trump announced  that he’ll meet with the National Rifle Association to discuss banning people on the terror and no-fly watch lists from purchasing firearms.

The announcement came in a tweet in the morning, roughly 90 minutes before Senate Democrats launched a filibuster to prompt action on the same issue, which is regaining attention after the Orlando massacre in which the gunman slaughtered 49 people and injured 53 others inside an LGBT nightclub.

“I will be meeting with the NRA, who has endorsed me, about not allowing people on the terrorist watch list, or the no fly list, to buy guns,” Trump tweeted.

His unprompted announcement pressures the gun lobby to help reach a compromise on the contentious proposal in the wake of the worst mass shooting in American history. 

While the gunman, Omar Mateen, was not on a terror watch list at the time of the shooting, he had previously been investigated by the FBI..

The NRA endorsed Trump last month, marking the earliest the group’s lobbying arm has backed a presidential candidate.

“The people that head up the NRA are great people,” Trump told supporters Wednesday afternoon during a rally in Atlanta. “And they love this country, and I told you we’re going to protect that Second Amendment, because it is under siege.” 

Though Trump’s proactive stance on the terror watch list issue is new, he has previously expressed his support of such a ban. Following November’s terrorist attacks in Paris in which 130 people died, Trump backed a Democratic-pushed measure to bar people on the watch list from purchasing guns.

It’s not known whether Trump will push for a form of the ban that will be palatable to Democrats, but his general stance aligns with President Barack Obama.

“The president does believe that the notion of preventing people who are on the no-fly list from buying a gun is a pretty common sense proposition,” White House press secretary Josh Earnest told reporters, though he notably deflected questions about Trump’s NRA meeting. 

“It is the kind of thing that even people who have profound political differences should be able to agree on,”

Trump’s position appeared to signal a shift from the NRA, which had dismissed such bans just one day ago as “ineffective” or “unconstitutional,” if not both.

“Restrictions like bans on gun purchases by people on ‘watch lists’ are ineffective, unconstitutional, or both,” the NRA tweeted Tuesday.

By Wednesday, however, the NRA tweeted that it was “happy to meet” Trump to discuss the issue, though it later made clear that the announcement did not represent a change.

“Our position is no guns for terrorists—period,” the association wrote. “Due process & right to self-defense for law-abiding Americans.”
