Fifty-six percent to 33 percent, more say they trust Mueller’s version of the facts than Trump’s. And by nearly as wide a margin, more believe Mueller is mainly interested in “finding out the truth” than trying to “hurt Trump politically.”…

Depending on what Mueller finds, the public seems to view the stakes as high, according to the poll, conducted last week by The Post and the Schar School of Policy and Government at George Mason University. More than 6 in 10 say that if Mueller concludes Trump obstructed justice or authorized his campaign to coordinate with Russians in an effort to win the 2016 election, Congress should begin impeachment hearings to remove him from office. House Speaker Nancy Pelosi (D-Calif.) has taken a cautious approach to addressing questions on the topic, saying in a recent NBC interview, “We shouldn’t be impeaching for a political reason, and we shouldn’t avoid impeachment for a political reason.”

Just over 4 in 10 Americans believe Mueller has proved members of Trump’s presidential campaign lied about contacts with Russians, and views on that question split sharply on partisan lines. More than 6 in 10 Democrats believe Mueller has proved Trump campaign members lied about such contacts, while more than 7 in 10 Republicans say he has not.
