Virginia lieutenant governor and Morrison & Foerster partner Justin Fairfax vehemently denied allegations of sexual assault Monday, even as a different political scandal appeared poised to unseat his boss and thrust him into the governorship.

Big League Politics, a political blog run by a former Breitbart News reporter, published a report Sunday tying Fairfax to an alleged sexual assault during the 2004 Democratic National Convention. The assault was described in a private Facebook post by a woman who did not name her alleged attacker.

The Washington Post on Monday confirmed that the woman had also brought her allegations against Fairfax to the newspaper after he was elected in November 2017, but it did not run a story because it could not corroborate her account or uncover similar accusations by others. The Post said Fairfax had described the encounter as consensual, an assertion he repeated to reporters Monday.
