For the most part, Republican candidates for Congress have been quiet about the immigration crisis on the border, with a few exceptions. But Rep. Tom Cotton, the GOP Senate candidate in Arkansas, has put his Democratic opponent’s support for amnesty for illegal immigrants at the center of his new TV ad.

“Senator Mark Pryor voted for amnesty, citizenship for illegals” says the ad’s voiceover. “Pryor voted against a border fence three times, and now Pryor ignores the crisis.” The ad then shows a clip from July 20.
