Trump smears John McCain in Sunday morning tweet: He was 'last in his class' and 'working' with Dems

President Donald Trump on Sunday asserted that deceased Sen. John McCain (R-AZ) had been "working" with Democrats before his death to undermine the president's administration.

In a tweet, Trump said that it had been "proven in court papers" that McCain was "last in his class" at Annapolis Naval Academy.

He went on to claim that McCain had been behind a dossier of damaging information about Trump. The dossier was created during the 2016 campaign.

"Even the Fake News refused this garbage!" Trump exclaimed in the tweet.
