At a campaign event outside of Detroit, GOP Sen. Ted Cruz of Texas attempted to tie Democratic candidate Abdul El-Sayed to the Muslim Brotherhood — a claim El-Sayed has repeatedly denied.

“My nickname for the guy is the jihadist leprechaun,” Cruz said about El-Sayed.

Cruz later said that El-Sayed would get top-level security clearance as a U.S. Senator if elected, claiming that El-Sayed could be put on the Senate Intelligence Committee, “and if I am correct that he is a passionate supporter of the Muslim Brotherhood, there is a very real risk that Americans will die as a result.”
