Media advocacy group Freedom of the Press Foundation has sent a warning letter to Paramount mogul Shari Redstone, outlining plans to file a lawsuit if the media company settles a suit brought by President Donald Trump against its subsidiary, CBS. Stern issued the warning by asking for a litigation hold on Friday afternoon, demanding that Paramount preserve any documents relating to a potential Trump deal and urging the company not to settle. Last October, President Trump sued Paramount subsidiaries CBS Broadcasting and CBS Interactive, alleging that an interview with former Vice President Kamala Harris that aired on longstanding CBS News program 60 Minutes was deceptively edited, in a manner that constituted election interference. Last week, Democratic senators Elizabeth Warren, Bernie Sanders, and Ron Wyden sent a letter to Redstone seeking information about any potential settlement, raising concerns that it would amount to bribery. Longtime 60 Minutes executive producer Bill Owens abruptly resigned in April, and CBS News president and CEO Wendy McMahon resigned earlier this month.
