Lawyers for President Donald Trump wasted no time firing off a demand letter after MSNBC’s Lawrence O’Donnell on Tuesday night made allegedly “false and defamatory statements that ‘Russian oligarchs’ co-signed loans provided to Mr. Trump by Deutsche Bank, and described these ‘co-signers’ as ‘Russian billionaires close to Vladimir Putin.’”

“If true, that explains every kind word Trump has ever said about Russia and Putin,” O’Donnell wrote in a follow-up tweet.
