Last night, under the obvious and vindictive orders of Donald Trump, United States Attorney General Jeff Sessions fired FBI Deputy Director Andrew McCabe just two days before his retirement. In what was nothing but a political ploy to try and discredit the FBI and the Special Counsel investigation into the Trump-Russia probe, Trump may have just fallen into a trap laid down by Robert Mueller – with the help of Jeff Sessions, who was interviewed by Mueller in the Trump-Russia probe last January.

It is no secret that Donald Trump has been targeting McCabe since he backed James Comey in corroborating Comey’s series of events that led to him being fired by Trump and the subsequent aftermath that followed. This has become one of the main targets of Mueller’s investigation into Trump’s obstruction of the investigation. Trump, with the telltale poker face of a Sam Nunberg, a la Barney Fife (Don Knotts), may have moronically, ignorantly and arrogantly given a foreboding outline of McCabe’s firing when he tweeted out his intentions on December 23, 2017, saying,“FBI Deputy Director Andrew McCabe is racing the clock to retire with full benefits. 90 days to go?!!!”

Knowing Donald Trump’s thirst for revenge, could Mueller have set a trap off that tweet, knowing that Trump is as transparent as a cheap novel and unable to restrain his thoughts and intentions? If I were Mueller, I would have prepared for it. Mueller did have George Papadopoulos wired up after he flipped him. Trump has not been kind to Sessions of late, and there is no law saying that a sitting Attorney General can’t be wired to help with an investigation, especially someone like Sessions who has been under scrutiny since lying under oath to Congress about meeting with the Russians.

There is a strong possibility that Robert Mueller was ready for this Trump move on McCabe, and Sessions could have been wired for his conversations with Trump since January. If Mueller was ready, then the obstruction case is complete, from the Comey firing to the McCabe firing. Mueller will not need to interview Trump now and ask him his intentions on his firing Comey, if he has them on tape and ready for prosecution. — Frank V.
