Sen. Robert Menendez contacted the U.S. Justice Department in an effort to delay a proposed merger opposed by one of his biggest campaign contributors, according to a letter obtained under the federal Freedom of Information Act.

Menendez and two House colleagues urged then-Attorney General John Ashcroft in September 2002 to postpone any decision “until a complete review of the merger can be done,” according to the letter. It followed an identical letter sent to Federal Communications Commission Chairman Michael Powell, which Bloomberg reported on here.

Menendez, then a U.S. representative, was aligned with Spanish Broadcasting System Inc. in objecting to a merger between Univision Communications Inc. and Hispanic Broadcasting Corp. At the time, Menendez owned from $1,000 to $15,000 in SBS stock.
