A former Justice Department official is speaking out after Mueller testified in his first public appearance since his firing in May.
Mueller, who was fired by President Donald Trump in May, said he had received a request from the Senate Judiciary Committee that he testify.
Muller said the Judiciary Committee requested his testimony because it wanted to review evidence relating to possible obstruction of justice related to his actions in the 2016 election.
Mulcahy’s testimony came a day after President Donald J. Trump, Jr., testified that he didn’t believe that former National Security Adviser Michael Flynn had lied to the FBI about his contact with a Russian lawyer during the 2016 presidential campaign.
“The FBI and the Department of Justice have conducted their investigations thoroughly,” Mueller said in a statement.
“As a result, I cannot speak to the details of any case or individual’s interactions with the Russians, but I do have a duty to defend the integrity of the FBI and Department of the Justice and to provide the American people with a fair, thorough, and impartial hearing.”
Mullers testimony came the day after Attorney General Jeff Sessions said in an interview that he wouldn’t recuse himself from the Russia probe if Trump had asked him to do so.
Sessions has faced growing pressure to recuse over his meeting with Russian Ambassador Sergey Kislyak in December.
Trump has denied any wrongdoing.
Saying the Senate investigation into his meetings with the Russian ambassador, Sessions, then-Sen. Al Franken (D-Minn.) and other Democrats urged Mueller to take more time to answer questions about his meetings.
Mueller said he was not obligated to recede from the probe, but that he would take the time to examine the material and the witnesses.
Mouthing off during a news conference on Tuesday, Mueller said his office had not yet found any evidence of criminal conduct by Trump.
But he did say there had been an effort to obstruct justice.
“It’s been clear that the president and his administration were trying to obstruct the investigation, that they tried to impede and impede,” Mueller testified.
“They have repeatedly said that this investigation was a witch hunt.
They have said that I am a political hack.
They said that there was an effort by Democrats and the media to destroy me and my family and my reputation.
And that this is all a conspiracy.”
Mueller said he would cooperate with the Senate probe and said he “was not a partisan lawyer.”
“The truth will come out and the truth will set the record straight,” Mueller added.
