Wallace pointed out that Sessions's recusal did not immediately lead to Mueller’s Russia probe, saying that the investigation was the result of Trump firing FBI Director James ComeyJames Brien ComeyChris Wallace on Yovanovitch testimony: 'If you're not moved, you don't have a pulse' Day one impeachment hearings draw 13.1M viewers, down 32 percent from Comey hearings There are poor ideas, bad ones and Facebook's Libra MORE.

“You know, things have changed, and obviously the decision in the spring of 2017 to recuse himself and everything that has flowed from that has made a big difference,” Wallace said. 

“Remember, the recusal of Sessions did not lead to the special counsel. It was the firing of Comey, of James Comey, the FBI director that led to the appointment of the special counsel,” he pointed out.

Sessions, the former Alabama senator who served as a top Trump campaign adviser, recused himself from the Russia investigation in March 2017 after it was revealed he failed to disclose a conversation he had with the Russian ambassador during the 2016 race.

Since then, multiple outlets have reported the president has privately pressured Sessions, whom he has frequently railed against in interviews, to reverse his decision to recuse himself. 

Those comments, in addition to his recent sting of tweets attacking Sessions, are reportedly under investigation as Mueller looks into whether Trump has obstructed justice.

Earlier this week, reports emerged alleging that the president was floating the possibility of firing Sessions to White House aides.

Trump later told Bloomberg in an interview published on Thursday that he will keep Sessions in his position until at least the upcoming midterm elections.
