Things like that never remain confidential for long in Washington. It leaks like a sieve.
From the article..This stinks to high heaven!!
While additional details about the letter were scarce, two media outlets have reported that the person who wrote the letter is being represented by an attorney, Debra Katz, who has been described in media reports as Washingtons #MeToo lawyer.
Katz has not responded to a request for comment from the Guardian. BuzzFeed reported that she was seen on Capitol Hill on Wednesday night, shortly after the Intercept first reported the existence of the letter.
