By the end of the hearing, it looked as if Sessions had gotten himself to a safe exit - at least in terms of legislative oversight.
White House deputy press secretary Sarah Huckabee Sanders told reporters aboard Air Force One as President Trump flew back from Milwaukee today that he watched parts of the hearing, "thought that Attorney General Sessions did a very good job and, in particular, was very strong on the point that there was no collusion between Russian Federation and the Trump campaign".
This was among the many times Sessions attempted to explain that he is protecting the President's right to choose to invoke executive privilege in not sharing the details of conversations.

Two months after his recusal, Mr. Sessions signed off on Mr. Comey's firing.
As a former Trump campaign surrogate, Sessions insisted he kept to his recusal from the Russian Federation probe even while he had a hand in firing James Comey as FBI director - which Trump later justified based on the Russian Federation investigation.
Testifying at a Senate hearing, Mr Sessions said it was a "detestable and appalling lie" to suggest that he participated in or was aware of any collusion between Russian Federation and the Trump campaign.
Sessions said it would be "absurd" to suggest that a recusal from a single investigation would render him unable to manage the leadership of the FBI.
