Few voters are praising Attorney General William Barr for how he has handled the release of the Mueller report, according to a new poll that comes amid Barr’s escalating clash with Congress.

Fewer than three in 10 voters — 29% — approve of the way Barr has handled the release of the report, the Politico/Morning Consult poll shows. Disapproval of Barr, meanwhile, is at just 39% — with nearly a third of voters, 32%, expressing no opinion. The attorney general released a redacted version of the report in mid-April but House Democrats have pressed him to release the unredacted version. House Judiciary Committee Chairman Jerrold Nadler said Tuesday that his panel is still planning to vote Wednesday to hold Barr in contempt of Congress.
