Clip shows Rep. Tony Gonzales' GOP rival making Nazi jokes, marching to German song

Brandon Herrera — the gun-loving social media influencer running against South Texas U.S. Rep. Tony Gonzales — made Holocaust jokes and marched to a World War II-era German song in a resurfaced YouTube video first reported on by news site JewishInsider. Herrera, known to followers as the "AK Guy," will face off with Gonzales in next month's Republican primary runoff to represent the 23rd District, which includes part of San Antonio and much of the U.S.-Mexico border. Herrera is running to the right of Gonzales, a moderate who lost some GOP support after he voted in favor of a major gun-control package and a bill protecting gay marriage.
