Judge Reggie Walton suggested the documents would be a distraction for a jury, The Washington Post reported.
"I'm just not going to let this case turn into a judicial resolution of the legitimacy of the war or the accuracy of the president's State of the Union address," Walton said.
Wilson -- sent to Niger to check on a report that former Iraqi leader Saddam Hussein had tried to buy yellowcake uranium in the African nation -- concluded that the reports was false. After President George W. Bush cited the Niger yellowcake claim in his 2003 State of the Union address, Wilson went public with an op-ed piece in The New York Times.
Libby's lawyer, Ted Wells, says he hopes to prove that Wilson lied about his findings.
