President George W. Bush nominated Connaughton to serve as Commissioner of the Federal Maritime Commission. Congress did not take up the nomination.

 Early career
Immediately upon graduation from the United States Merchant Marine Academy, Connaughton accepted a Commission as an Officer in the United States Coast Guard, remaining on Active Duty until 1986 when he joined the United States Naval Reserve. He continued to serve in the Coast Guard as an Assistant Branch Chief in the marine safety area. Connaughton entered private legal practice in 1992. His legal career is highlighted by his service as Co-counsel on the case Intertanko v. Locke, winning a unanimous decision before the United States Supreme Court
 Chairman of the Prince William Board of County Supervisors

The Washington Post characterized Connaghton as a "pragmatist" during his tenure. Connaughton capped the growth of all real estate taxes at 5.9%, despite double-digit growth in real estate value and the jurisdiction achieved a AAA Bond Rating. He also successfully campaigned to bring AOL, General Dynamics, Comcast, Eli Lilly and other major employers to Prince William.
 Maritime Administration
In September 2006, Connaughton assumed the helm of the Maritime Administration. He focused on laying the foundation for a marine highways system, greater opportunities for American mariners, and a reorganization of the agency to make it more effective are significant steps he’s taken during his watch. During his tenure Connaughton was consistently cited as one of the best Federal transportation policy leaders by Members of Congress, industry and the media.
