Representative Alan Grayson, Democrat of Florida, may have improperly used his House office and staff to handle personal financial matters involving a family-run hedge fund as well as political activities related to his bid for the United States Senate, the Office of Congressional Ethics concluded in a 986-page investigation released Tuesday.
The report, which found as many as a half dozen violations of House rules,provoked an angry response from Mr. Grayson, who accused the quasi-independent agency of conspiring with his Democratic opponent for the Senate seat.
