Cassidy & Associates lobbyist Todd Boulanger, a former aide to ex-Sen. Bob Smith (R-N.H.) who went on to work with disgraced lobbyist Jack Abramoff, abruptly left his firm Friday.

Another former Congressional aide, Trevor Blackann, 34, pleaded guilty Thursday to filing a false tax return that omitted at least $4,100 in illegal gifts from lobbyists. Blackann, a onetime aide to Missouri GOP Sen. Kit Bond and Rep. Roy Blunt, admitted to taking accepting gifts, including a trip to New York to see a World Series baseball game and "admission to and entertainment at" a strip club, according to court documents.
