Agree, I don't think he's talking about the Nobel committee.
Has to be "nobles" are the ruling elites in the publishing industry. They awarded prizes (Pulitzer) to journalists who toed the correct narrative, or the elites line.
POTUS has proof those awards were for incorrect information and he has that information available. If the elites don't make printed corrections and rescind the false awards they would be 'knowingly' disseminating false information designed to undermine the US government.
Big warning.
