Robert Mueller Arrives for Congressional Hearing on Russia Investigation

Former special counsel Robert Mueller arrives at Capitol Hill to testify before Congress on Russian meddling in the 2016 presidential election on behalf of President Donald Trump.

A day of drama is unfolding Wednesday, July 24, in Washington, with former special counsel Robert Mueller testifying before Congress about Russian meddling in the 2016 presidential election on behalf of Donald Trump and whether Trump subsequently obstructed justice as president by trying to thwart the prosecutor’s investigation.

Mueller, a reluctant witness, has already said, “The report is my testimony,” so it is unclear how much new information might emerge from Wednesday’s hearings. The Justice Department on Monday sent Mueller a letter emphasizing that he “must remain within the boundaries” of the public version of his report and could not “discuss the conduct of uncharged third parties.”

Still, lawmakers could ask Mueller why he did not subpoena Trump to give face-to-face testimony, even though Trump said several times he was willing to testify. Trump answered written questions about his campaign, but refused to answer questions about his alleged obstruction. Trump has claimed to have the “world’s greatest memory.” Yet of the the more than 65 written questions posed to him, Trump said more than 30 times that he had no recollection.

But Mueller appears unlikely to answer the biggest question of all, whether he would have charged Trump with obstruction of justice were it not for the long-standing Justice Department policy prohibiting filing criminal charges against a sitting president.
