Sean Carroll reports that Massa's chief of staff, Joe Racalto, was interviewed by the House Ethics Committee around February 9. In Sean's earlier interview, Racalto had used some evasive language on the ethics investigation, but now that it's been officially announced, he acknowledged that it's been going on for a while.
Massa's press operation, which typically cranks out a couple of press releases every day, has been silent since Wednesday's press conference.
