As the video opens, Democratic Texas State Rep. James ?Talarico appears to stand in front of a Texas flag, beaming.

¡°Radicalized white men are the greatest domestic terrorist threat in our country,¡± the U.S. Senate candidate seems to say into the camera. As a voice whispers ¡°white men,¡± Talarico continues: ¡°So true. So true.¡±

But Talarico never filmed that video. Instead, the clip is an artificial intelligence-generated ad from the National Republican Senatorial Committee (NRSC), the party¡¯s Senate campaign arm, featuring a computer-altered Talarico reciting social media posts he wrote years ago. The words ¡°AI generated¡± show up in easy-to-miss font in the lower right-hand corner.
