Gun rights advocate John Lott Jr. said in an interview that aired Monday on Hill.TV's "Rising" that a Democratic president would possibly declare a national emergency on gun violence in order to confiscate firearms.

"I'd see that [as] quite possible," Lott Jr., the author of "The War on Guns," told host Buck Sexton last week at the Conservative Political Action Conference (CPAC).

"You've seen California, New York, Chicago and other places in the United States that have already used registration lists that they've had to identify people that owned guns to force them to have to turn them in, and get rid of them," he continued.

"It wouldn't be a stretch at all to see something like that happening nationally," he said.

Many Republicans have argued that Trump's declaration could set a precedent for future Democratic presidents to declare national emergencies on issues such as gun violence.

"A Democratic president can declare emergencies, as well," Pelosi said. "So the precedent that the president is setting here is something that should be met with great unease and dismay by the Republicans."

A number of Democrats in the 2020 primary field have pledged to take action on gun control if elected.
