Comey testifies that Trump was never under investigation
So why did Sessions recuse himself?
Jefferson Sessions Statement, June 13, 2017
Let me also explain clearly the circumstances of my recusal from the investigation into the Russian interference with the 2016 election. I was sworn in as Attorney General on Thursday, February 9th. The very next day, I met with career Department officials, including a senior ethics official, to discuss some things publicly reported in the press and that might have some bearing on the issue of recusal. From that point, February 10th, until I announced my formal recusal on March 2nd, I was never briefed on any investigative details and did not access information about the investigation; I received only the limited information that the Department's career officials determined was necessary to inform my recusal decision. As such, I have no knowledge about this investigation beyond what has been publicly reported, and I have taken no action with regard to any such investigation. On the date of my formal recusal, my Chief of Staff sent an email to the heads of the relevant departments, including by name to Director Comey of the FBI, to instruct them to inform their staffs of this recusal and to advise them not to brief me or involve me in any such matters. And in fact, they have not. Importantly, I recused myself not because of any asserted wrongdoing on my part during the campaign, but because a Department of Justice regulation, 28 CFR 45.2, required it. That regulation states, in effect, that Department employees should not participate in investigations of a campaign if they have served as a campaign advisor.
