Former Rep. Beto O’Rourke (D-Texas) accused a Texas state lawmaker of issuing a “death threat” after last night’s debate.

During the debate, O’Rourke took a strong stance on gun control, at one point saying:

“When we see that [assault weapons] being used against children, and in Odessa, I met the mother of a 15-year-old girl who was shot by an AR-15, and that mother watched her bleed to death over the course of an hour because so many other people were shot by that AR-15 in Odessa and Midland, there weren’t enough ambulances to get to them in time, hell, yes, we’re going to take your AR-15, your AK-47.”

“We’re not going to allow it to be used against our fellow Americans anymore.”

After that incident, Texas state legislator Rep. Briscoe Cain (R) quoted his response and added: “My AR is ready for you, Robert Francis,” referring to O’Rourke’s birth name.

In response, Beto O’Rourke tweeted:

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

The original tweet was then taken down by Twitter for violating its terms and conditions, said the site.

O’ Rourke’s campaign have reported the tweet and the threat to the FBI, they confirmed to The Guardian.

But the Texas lawmaker’s Twitter account remains active and other tweets referring to the threat were not taken down.
