A dying John McCain continued doing his best in pushing the false Steele anti-Trump dossier to James Comey.

Breitbart: IG Report Reveals Steele Funneled Claims Through John McCain After FBI Dropped Him.

Late Senator John McCain provided disgraced former FBI chief James Comey with five separate reports from Christopher Steele that the FBI didn’t previously possess related to unsubstantiated allegations of collusion between Russia and President Trump’s 2016 campaign, the Justice Department’s recent Inspector General report revealed.

There have long been questions about why it was necessary for McCain to pass Steele’s anti-Trump dossier to Comey on December 9, 2016, several weeks after the November 2016 presidential election. By then, Steele had already met numerous times with FBI agents to provide them with his controversial reports. Steele, however, was terminated as an FBI source in the fall of 2016 because he spoke to the news media.

The IG report also verifies that a McCain aid obtained the Steele reports directly from Fusion GPS co-founder Glenn Simpson, meaning that when McCain transferred the anti-Trump charges to Comey he had to have known that the material originated with a firm that specializes in controversial opposition tactics.

States the IG report:

    Several weeks later, on December 9, 2016, Senator John McCain provided Corney with a collection of 16 Steele election reports, 5 of which Steele had not given the FBI. McCain had obtained these reports from a staff member at the McCain Institute. The McCain Institute staff member had met with Steele and later acquired the reports from Simpson.

Prior to his death, McCain admitted to personally handing the dossier to Comey but he refused repeated requests for comment about whether he had a role in providing the dossier to BuzzFeed, including numerous inquiries sent to his office by this reporter.

In his book published last year, McCain maintained he had an “obligation” to pass the dossier charges against Trump to Comey and he would even do it again. “Anyone who doesn’t like it can go to hell,” McCain exclaimed.

Doing work so dirty even the DEMS didn't want to touch it. But McCain? He was only too happy and eager to oblige. And with pride...while he was dying.

You're handed a death sentence - a terminal diagnosis. You have limited time remaining on this planet. Who spends that time consumed with hatred and bitterness for a person they define as their "political nemesis"? You'd have to ask the McCain family, especially daughter Meghan and The Widow Cindy.
