Democrat presidential candidate Robert Francis “Beto” O’Rourke is accusing Republican Texas state Rep. Briscoe Cain (HD-128) of making a death threat against him over his plan to ban, “buy back” and confiscate AR-15 rifles.

ABC’s David Muir asks Beto O’Rourke about his plan to ban AR-15s.

O’Rourke replied, “This is a death threat, Representative. Clearly, you shouldn’t own an AR-15—and neither should anyone else.”

Cain also replied to a supporter who noted he was getting ratioed for defending the Second Amendment, “I get ratioed in the reg. Good summary though. Come and take it!”

O’Rourke spoke about his AR-15 and AK-47 ban at Thursday’s debate in Houston.

Hell yeah, we're going to take your AR-15. If it's a weapon that was designed to kill people on the battlefield, we're going to buy it back. pic.twitter.com/cCEWkG6y0X — Beto O'Rourke (@BetoORourke) September 13, 2019

O’Rourke followed the debate with an appearance on MSNBC.

You can't own a grenade launcher or drive a tank down the street. These AR-15s and AK-47s are weapons of war—and we need to buy back every single one of them. pic.twitter.com/RjB9FUuXjR — Beto O'Rourke (@BetoORourke) September 13, 2019

O’Rourke is fundraising off the proposed gun ban.

UPDATE: Twitter deleted Cain’s “My AR-15 is ready for you Robert Francis” tweet. A link was instead provided to Twitter rules and enforcement.
