Democratic Rep. Maxine Waters is asking the Justice Department to investigate the source of the letter posted to Twitter by her top GOP competitor that falsely alleges she wants to resettle “up to 41k” refugees in her California district.

Omar Navarro, the Republican candidate being backed by many far-right donors, tweeted out the document, a forgery, on Monday with an attached caption.

“According to this document, Maxine Waters wants more terrorists, like the one who bombed NYC, in California’s 43rd District,” Navarro tweeted.

“As Congressman of CA’s 43rd District, I will oppose such policies.”

The tweet has been re-tweeted more than 700 times.
