Texas Republican tells Beto "My AR is ready for you" in response to gun confiscation vow

“Hell yes, we’re going to take your AR-15, your AK-47,” O’Rourke said during the third Democratic primary debate in Houston.

O’Rourke responded to Cain’s tweet by arguing that the message alone should disqualify him from owning an AR-15.

Twitter deleted Cain’s tweet roughly two hours after it was posted because it violated the company’s prohibition against issuing violent threats.

O’Rourke’s campaign told CNN that it plans to report Cain’s message to the FBI.
