The many missions of Jeff Sessions

All Attorney General Jeff Sessions has to do to in his dramatic Tuesday testimony before the Senate is tell the truth, stay loyal to President Trump, explain his possible unreported meeting with Russian officials last year, dismiss worries that his ties to Russia are "problematic," and somehow try to keep his job.

Sessions will deliver his long-awaited testimony before the Senate Intelligence Committee on Tuesday afternoon, a day Sessions himself lobbied for in an apparent attempt to avoid testifying at two other budget hearings the same day. That move didn't win him any friends in Congress, and several members said Sessions should also testify in different committees on Russia, the 2016 election and Trump.

Those complaints on Monday only seemed to contribute to the idea that Sessions is running out of allies. Some reports have suggested that Sessions has already mulled resigning amid growing tensions with Trump over his decision to recuse himself from any investigation dealing with the campaign, which eventually led to the creation an special counsel to examine these issues.

But many in the Senate are just as unhappy. Last week, after public testimony at the same Senate Intelligence Committee that Sessions will meet with today, former FBI Director James Comey said he was unable to discuss openly issues related to Sessions that make his involvement in any Russia investigation "problematic."

In a closed meeting, Comey reported said Sessions had a third, unreported meeting with Russian Ambassador Sergei Kislyak, and senators are ready to ask Sessions today why that was never reported.
