Fifty-six percent say they think questions still exist about Trump, while 9 percent say they are unsure.

The poll showed broad support for the release of the full report, the culmination of Mueller's investigation into Russian interference in the 2016 presidential election, but showed a mixed response to questions about what Democrats should do next.

"People clearly want to see more about the report," said Lee Miringoff, director of the Marist Institute for Public Opinion, which conducted the poll for NPR and PBS. "They want it released publicly, are eager to see the principals — Mueller and Barr — testify, because they want to see how the sausage was made. They want to see how we got to this point."

Forty-eight percent of those polled want Democrats to hold hearings to further investigate, while 45 want the investigations to end. A remaining 7 percent say they are unsure what Democrats should do next.

Regarding their thoughts on Mueller and how he handled the 22-month probe, 56 percent said Mueller conducted a fair investigation while 51 percent said they were satisfied with it, including 52 percent of independents.

When asked if Mueller should testify before Congress to testify about the findings, 64 percent said yes, while just 28 percent said no.

When asked the same question regarding Barr testifying before Congress, 66 percent believe he should, while an identical 28 percent said no.

The poll shows President Trump's approval at 42 percent, up 3 points from the previous month.

Barr's four-page summary revealed that Mueller did not find evidence of a conspiracy between Trump's campaign and Moscow to influence the 2016 presidential election.

Mueller did not make a finding on whether Trump obstructed justice, but Barr determined after reviewing the report that there should be no charge.

Trump has taken a victory lap over the conclusions, while Republicans have promised new investigations into how the probe started.

"Robert Mueller was a god to the Democrats — was a god to them until he said no collusion,” the president told supporters at a rally in Grand Rapids, Mich. “They don’t like him so much right now."
