A Louisiana Republican congressional candidate endorsed by Donald Trump was the subject of a 2007 rape accusation that was reported to local law enforcement the same day of the alleged assault – but never disclosed to the public or, reportedly, the president’s team as he became one of the rising stars in the state’s Republican party.

That has raised concerns within the White House that Blake Miguez “either wasn’t fully vetted or wasn’t forthcoming about discoverable documents from his past” before securing Trump’s backing, the Atlantic reported on Wednesday, citing two unnamed sources familiar with the endorsement process.

Miguez’s campaign told the Atlantic it denied the allegations by a woman who described him as a “live-in ex boyfriend” at the time. The claims did not result in any formal criminal charges after the accuser said she refused to press charges against Miguez – then in law school – because she did not want to get him into trouble, according to what investigators wrote in a police report obtained by the Guardian through a public records request.
