The New York Times misrepresented a comment made by Sen. Joseph I. Lieberman (D-CT) to falsely report that Lieberman had said he would likely support John G. Roberts Jr.'s nomination to the Supreme Court. In a July 20 article, Times reporter Adam Nagourney referred to a Lieberman quote that appeared in a July 14 Hartford Courant article. Nagourney wrote: "Even before the nomination, Senator Joseph I. Lieberman of Connecticut, a moderate Democrat and one of the 14 senators whose recent compromise averted a shutdown on the process of confirming judicial nominees, said he was likely to support Mr. Roberts if he was nominated."
But in fact, the Courant reported that Lieberman had said that Roberts was "in the ballpark" of potential Supreme Court justices who could be considered without sparking a filibuster. Far from offering an endorsement, Lieberman insisted that Roberts "would be carefully scrutinized":
Lieberman offered reporters Wednesday three names he said could be considered without sparking a talk-athon. He would not say whether he brought them up to Rove.
He said federal appellate Judges Michael McConnell and John G. Roberts were "in the ballpark," and that "people tell me" appeals court Judge J. Harvie Wilkinson is "very similar."
Lieberman emphasized that should they be nominated, they would be carefully scrutinized.
