A House committee broadened its investigation into government-subsidized train operator Amtrak’s legal department and its outside legal counsel last week, calling for the Justice Department to investigate possible illegal activities.

In a Dec. 4 letter obtained by Legal Times, outgoing House Transportation and Infrastructure Committee Chairman Don Young, R-Alaska, and committee member Rep. John Mica, R-Fla., requested that Attorney General Alberto Gonzales review “what may constitute unlawful conduct” between Amtrak’s legal team and outside law firms. It’s the second letter the lawmakers have sent regarding potential mismanagement on the part of Amtrak and its outside law firms.
