The 40-page brief, filed in the U.S. Court of Appeals for the District of Columbia Circuit, argues that there is "ample evidence . . . to doubt that a crime has been committed" in the case, which centers on the question of whether Bush administration officials knowingly revealed the identity of undercover CIA operative Valerie Plame in the summer of 2003. Plame's name was published first by syndicated columnist Robert D. Novak and later by other publications.

The friend-of-the-court brief was filed by 36 news organizations, including The Washington Post and major broadcast and cable television news networks, in support of reporters at the New York Times and Time magazine who face possible jail time for refusing to cooperate with a grand jury investigating the allegations. Those two organizations filed a petition Tuesday asking the full appeals court to review the case.

A three-judge panel of the D.C. Circuit ruled in February that two reporters -- Judith Miller of the Times and Matthew Cooper of Time -- should be jailed for contempt if they continued to refuse to name their sources to the grand jury.
