Mueller: Investigation Did Not Exonerate Trump of Alleged Obstruction Ken Bredemeier This story was updated on July 24 at 12:31 pm WASHINGTON - Former special counsel Robert Mueller told Congress Wednesday that his investigation of Russian meddling in the 2016 U.S. presidential election did not exonerate President Donald Trump of allegedly obstructing justice by trying to thwart the probe, even though the U.S. leader has claimed it did. As hours of testimony started, House Judiciary Committee chairman Jerrold Nadler asked the prosecutor, "Did you totally exonerate the president?" "No," Mueller responded, later adding, "The president was not exculpated for the acts he allegedly committed." Mueller explained, however, that Trump could not be criminally charged because of a long-standing Justice Department policy prohibiting the indictment of a sitting president. Mueller said his team unsuccessfully tried for a year to reach agreement with Trump to give live, face-to-face testimony, but the president only answered some questions in writing. Later in the hearing, Republican Congressman Ken Buck asked Mueller, "You believe that he committed --- you could charge the president of the United States with obstruction of justice after he left office? "Yes," Mueller replied. Why Trump wasn't charged However, Mueller, hewing closely to the 448-page report his investigators compiled after a 22-month probe, acknowledged to Republican Congressman Doug Collins that his investigators concluded there was insufficient evidence to charge Trump or any of his 2016 campaign staff with conspiring with Russia to help Trump win a four-year term in the White House. Another Republican, Congressman James Sensenbrenner, attacked Mueller for continuing his probe even knowing that Trump could not be charged with a crime, although Mueller said that was permissible under Justice Department guidelines. "If you're not going to indict the president, then you're just going to continue fishing, that's my opinion," Sensenbrenner said. Mueller answered many questions with cryptic yes or no responses, saying he stood by the conclusions contained in his lengthy report. At one point he said, "I again go back to the text of the report," declining to further analyze his findings. Democrats expressed their belief that Trump obstructed justice, as outlined in the report. Republicans insisted Mueller's report had cleared the president and that the investigation was based on questionable intelligence before Mueller was named special counsel in May 2017. The Republicans cited a report paid for by Democrats containing largely unsubstantiated claims by former British intelligence officer Christopher Steele about Trump's time in Moscow before he entered politics. Mueller repeatedly said the origins of the Russia investigation, 10 months before he became special counsel, were "outside my purview." But shortly after Mueller acknowledged during his testimony that his investigation had not been impeded by the White House, Trump quickly said on Twitter, "In other words, there was NO OBSTRUCTION." NO COLLUSION, NO OBSTRUCTION! -- Donald J. Trump (@realDonaldTrump) [1]July 24, 2019 Who's watching? Millions of Americans tuned in for what proved to be a riveting day of contentious questioning before the House Judiciary and Intelligence Committees. The hearings are equally critical for the 235 opposition Democrats in the House of Representatives, more than a third of whom have called for Trump's impeachment or the start of an impeachment inquiry. These critics allege that the president committed "high crimes and misdemeanors" -- the standard for impeachment -- by trying to halt Mueller's 22-month probe. The Mueller report said the president directed then-White House counsel Donald McGahn to try to oust Mueller and then publicly lie that Trump had not told him to seek Mueller's dismissal. Mueller alleged that Trump directed his one-time campaign manager Corey Lewandowski to try to get then-Attorney General Jeff Sessions to limit the Mueller investigation. The report also alleged that the president possibly engaged in witness tampering to discourage two key aides convicted by Mueller's team, Trump personal attorney Michael Cohen and former campaign chairman Paul Manafort, from cooperating with investigators.
