Indicted Rep. Duncan Hunter (R-Calif.) is reportedly mailing letters filled with Islamophobic rhetoric about his Democratic opponent, Ammar Campa-Najjar, and two Muslim congresswomen to voters in his Southern California district.

The mailers, first reported by Politico, feature photos of Campa-Najjar, a Protestant, and Democratic Reps. Ilhan Omar (Minn.) and Rashida Tlaib (Mich.) alongside an image of one of the terrorists involved in a 1972 attack on Israeli athletes at the Munich Olympics. They also solicit contributions from recipients.

“Ilhan Omar, Rashida Tlaib and Ammar Campa-Najjar ... these three radical Democrats want you to forget their anti-semitism or family-terrorist ties!” reads a message on the back of the letters. “But as a Marine I’ll never forget the 1983 Beirut bombings and the 1972 Olympic murders!”

The letters reference allegations that Campa-Najjar’s grandfather, whom he never knew, was a Palestinian terrorist involved in the planning of the Munich attack. (Campa-Najjar has condemned both the attack and his grandfather’s alleged role in it, which has been recently called into question.)

Hunter’s office did not immediately respond to a request for his comment. But his spokesman, Michael Harrison, confirmed to Politico that Hunter’s 2020 reelection campaign sent the mailers.

“It is a piece put out by Congressman Hunter’s campaign,” Harrison said. “It’s a hard-hitting piece because these are significant issues that our opponent refuses to acknowledge.”

Asked to comment on the mailers, Campa-Najjar simply noted to HuffPost that the letters contain a spelling error where they claim Tlaib is “anti-Isreal.”

“His spell-checkers are as bad as his fact-checkers,” said Campa-Najjar, a 29-year-old fellow at the U.S. Immigration Policy Center at the University of California, San Diego.
