AUSTIN, Texas (AP) — A Texas state representative is being criticized for tweeting he had an assault weapon ready for Democratic president candidate Beto O’Rourke. The tweet by Republican state Rep. Briscoe Cain came after O’Rourke pledged during the Democratic debate that “hell yes, we’re gonna take your AR-15, your AK-47” when asked about a mandatory assault weapons buyback he’s endorsed. Twitter later took down Cain’s tweet.
