\'Mistake\' for Trump to criticize McCain: Graham

ROUGH CUT (NO REPORTER NARRATION) Republican Senator Lindsey Graham slammed U.S. President Donald Trump for his twitter posts on the late Arizona senator, where Trump berated McCain's intellect and claimed the release of a dossier was a "dark stain" on him "So it was indeed (just proven in court papers) "last in his class" (Annapolis) John McCain that sent the Fake Dossier to the FBI and Media hoping to have it printed BEFORE the Election," Trump tweeted on Sunday.

A day earlier, Trump tweeted that the release of a dossier was a "dark stain" on McCain.

The document was authored by former MI6 officer and alleged Moscow had attempted to interfere in the 2016 U.S. election and potential collusion between Russia and Trump, along with other unverified and salacious claims about the president.

Trump has in the past been ridiculed for his critical remarks of John McCain's legacy.
