Rep. Maxine Waters’ Republican challenger will speak with the FBI agents after he posted a fake letter that he said was from Waters.

Omar Navarro said he will talk with agents on Wednesday in his campaign office, the Los Angeles Times reported.

Waters asked the FBI to investigate the letter that falsely said she wanted to resettle tens of thousands of refugees in her district on the grounds that it is illegal to impersonate a federal official.

“I don’t know why they are looking into me since I’m not the one who fabricated the letter,” Navarro told the Times.

Despite saying he has not spoken with the person who created the letter since December, Navarro has not deleted the tweet.
