Members of a House committee peppered former special counsel Robert S. Mueller III with questions about President Donald Trump’s displeasure over the decision by then-Attorney General Jeff Sessions to recuse himself from oversight of an investigation into Trump and whether Russia interfered with the 2016 presidential election.

Mueller appeared before the House Judiciary Committee on Wednesday to answer questions about the report his office issued earlier this year about the investigation.

Sessions, who had been Alabama’s junior senator, was an early supporter of Trump’s presidential candidacy and campaigned for him during the Republican primary and general election. He resigned from the Senate when Trump appointed him attorney general.

He drew Trump’s ire, however, when he recused himself from having a role in oversight of the Russia investigation. The president fired Sessions last November.

Mueller today was questioned about Trump’s appeals to Sessions to intercede in the special counsel’s investigation, according to news reports on the hearing.

According to testimony and Mueller’s report, Trump told his former campaign manager, Corey Lewandowski, to get Sessions to limit Mueller’s investigation and declare Trump’s own activities off limits. The president told Lewandowski that if Sessions would not meet with him, he should give the attorney general the message that he would be fired.

Testimony this morning also went into instances when Trump asked Sessions to un-recuse himself and anger he expressed when Sessions refused, according to a transcript posted by the Washington Post.
