Most voters don't expect Mueller testimony to reveal new information

The majority of voters don’t expect former special counsel Robert MuellerRobert (Bob) Swan MuellerSchiff: Trump acquittal in Senate trial would not signal a 'failure' Jeffries blasts Trump for attack on Thunberg at impeachment hearing Live coverage: House Judiciary to vote on impeachment after surprise delay MORE’s testimony on Wednesday to reveal any new information, according to a Hill-HarrisX poll.

According to the survey released Tuesday, 65 percent of registered voters said they aren't expecting Mueller's public testimony before two House committees to include previously unknown details, while 35 percent think he will go beyond the scope of his 448-page Russia report.

When broken down by party, 49 percent of Democrats said they expect the testimony will reveal something new, compared to only 21 percent of Republicans who said the same.

Thirty-four percent of independents said the testimony will include new info about Mueller’s 22-month probe into Russian election meddling.

Republicans and Democrats are gearing up for Mueller’s highly anticipated testimony, which is expected to last about five hours.

Mueller has already stated he will stick to the findings of his public report, which had some portions redacted.

“The report is my testimony. I would not provide information beyond that which is already public in any appearance before Congress.” Mueller said during his May 29 statement to the press, when he also gave a summary of the report.

Mueller reiterated that his report found no evidence of collusion between Russia and the Trump campaign, but he did not make a judgment on whether Trump obstructed justice.

"As set forth in the report, after the investigation, if we had confidence that the president did not clearly commit a crime, we would have said so," he told reporters at the time.

Mueller’s spokesman has since emphasized that the former special counsel does not plan to go beyond the findings in his report.

“As I think he made crystal clear then, you can expect him to stick as much as he can to the four walls of the Mueller report,” said Jim Popkin, pointing to the May statement.

But House Democrats are nevertheless expected to press Mueller, who will be testifying as a private citizen.

In the days leading up to the testimony, the Justice Department has stepped in and told Mueller that he should limit his testimony to his report’s findings, saying anything beyond that would be protected by presidential privilege, which hasn’t been waived.

“Any testimony must remain within the boundaries of your public report because matters within the scope of your investigation were covered by executive privilege, including information protected by law enforcement, deliberative process, attorney work product, and presidential communications privileges,” Associate Deputy Attorney General Bradley Weinsheimer wrote in a letter to Mueller obtained by The Hill.
