The tweets followed an Axios report published late Saturday night claiming that former FBI Director Andrew McCabe - who was fired by Attorney General Jeff Sessions on Friday and was stripped of his pension benefits - had met with Mueller, who asked him about Trump's firing of Comey nearly a year earlier, and also turned over "contemporaneous" memos that he'd taken detailing his conversations with the president.
Trump claimed that Comey lied during public Senate testimony last Spring, when he said he'd never been an anonymous source for the news media - then admitted that he had "authorized" a friend to leak one of his memos to the New York Times, which Comey said he did in hopes of sparking a special counsel investigation.
In this particular case, Trump may be referencing what se discussed last night, namely that McCabe may himself have jeopardized Comey, a point underscored by constitutional law professor Jonathan Turley on CNN, who suggested that McCabe's statement following his firing "immediately" raised a flag, which may lead to serious consequences for his former boss. McCabe's statement reads in part:
The OIG investigation has focused on information I chose to share with a reporter through my public affairs officer and a legal counselor. As Deputy Director, I was one of only a few people who had the authority to do that. It was not a secret, it took place over several days, and others, including the Director, were aware of the interaction with the reporter.
