Rep. Ted Lieu, a Chinese-American Democrat from California, took umbrage at a new ad that he deemed “racist” from Rep. Chris Collins as the New York Republican tries to revive his campaign.

The ad in question shows Collins’ Democratic opponent, Nate McMurray, speaking Korean, with subtitles saying his goal was to ship jobs overseas when he was a lawyer in Korea. The subtitles did not at all match what McMurray was actually saying in the video. The ad has been all over Buffalo television screens over the last week.

“Take your racist ad and shove it,” Lieu, a U.S. Air Force Reserve colonel who spent time in Guam, where he coordinated defense with Korean officials, tweeted late Tuesday.

“You are an embarrassment to the House of Representatives,” Lieu wrote.
