The U.S. Supreme Court declined on Monday to revive a $300 million defamation lawsuit filed by attorney Alan Dershowitz against CNN regarding the network’s coverage of his remarks made while defending former President Donald Trump during the 2020 impeachment trial. The high court’s brief, unexplained order left in place rulings from lower courts that had dismissed the case.

Dershowitz, a retired Harvard Law School professor and legal commentator, was part of Trump’s legal team during the impeachment proceedings, which centered on allegations that Trump sought political favors from Ukraine in exchange for U.S. military aid. The Senate ultimately acquitted Trump.

The lawsuit alleged that CNN misrepresented Dershowitz’s comments in a broadcast, stitching together selective portions in a way that distorted his intended meaning. Specifically, Dershowitz had said, “the only thing that would make a quid pro quo unlawful is if the quo were somehow illegal,” and that providing arms to Ukraine was not illegal. However, Dershowitz asserted that CNN edited his remarks to suggest he argued that a president could commit illegal acts for reelection purposes without facing impeachment—a portrayal he called “preposterous and foolish on its face.”

CNN responded that the network aired Dershowitz’s full remarks during live coverage and further invited him on air twice more to clarify his position. The network maintained its reporting was accurate and contextualized.

Justices Neil Gorsuch and Clarence Thomas dissented from the Supreme Court’s decision not to hear the case, urging the court to reconsider the standard for defamation claims made by public figures. The majority, however, did not provide additional commentary.

Lower federal courts had ruled against Dershowitz, finding insufficient grounds to proceed with the defamation suit against CNN. The Supreme Court’s refusal to review the case effectively ends Dershowitz’s legal challenge over the network’s coverage.
