Michigan GOP Senate nominee Mike Rogers used his Thursday speech at the Republican midterm convention to accuse his Democratic rival, Abdul el Sayed, of aspiring to represent a foreign territory over the state they’re running to serve.

The remarks came amid a feud between the candidates over national security ahead of Friday’s 25th anniversary of the 9/11 terrorist attacks, with Rogers portraying el Sayed as a threat to the United States if sent to Washington and condemning his relationship with controversial Twitch streamer Hasan Piker, who once said America “deserved” 9/11 before walking it back.
