Wire reporting: (Reuters, via CNBC)

President Donald Trump, speaking Sunday in Port Huron, Michigan, attacked Democratic U.S. Senate nominee Abdul El-Sayed in religious terms while backing Republican Mike Rogers, Michigan Advance and CBS News reported^1,3.

Michigan Advance quoted Trump saying he was there to keep a jihadist and Muslim Brotherhood member from becoming a senator¹. CNBC, carrying Reuters, said he compared the race to United Flight 93 and named Michigan native Todd Beamer².

CNBC said El-Sayed, if elected, would be the first Muslim U.S. senator, and that he has denied Muslim Brotherhood affiliation, calling questions about his loyalty shameful². Rogers, on NBC's "Meet the Press" Sunday, said El-Sayed had not answered the allegations to his satisfaction².

The rally also featured gubernatorial candidate John James, Michigan Advance said, a day after former President Barack Obama campaigned for Michigan Democrats¹. The Senate contest is for an open seat in the Nov. 3 midterms².

Independent evidence for the Brotherhood claim was not presented in the reports reviewed. How the rhetoric affects turnout in Michigan is unknown^1,2.

Michigan Advance said Port Huron sits in one of the state's most Republican districts and that Rogers has also campaigned in Detroit¹. Arab News carried a similar account of Trump linking El-Sayed to extremists⁵.

CNBC said El-Sayed has run an ad defending his faith, saying Washington has too little of it². Al Jazeera labeled the Port Huron remarks an escalation of anti-Muslim campaigning⁴.

Neither Trump nor Rogers presented documents in these reports tying El-Sayed to the Muslim Brotherhood^1,2.
