Democrats in Congress attacked Attorney General William Barr on Wednesday night before the planned release of an edited version of the Russian interference report by Special Counsel Robert Mueller in the 2016 presidential election and allegations of collusion between the Trump campaign and Russian officials.

The Justice Department says Attorney General William Barr will hold a news conference Thursday morning on special counsel Robert Mueller’s Russia investigation, according to Associated Press.

The news conference will be held at 9:30 a.m. at the Justice Department in Washington. Barr will be joined by Deputy Attorney General Rod Rosenstein.

House Speaker Nancy Pelosi, D-Calif., tweeted that Barr “has thrown out his credibility & the DOJ’s independence with his single-minded effort to protect ⁦‪@realDonaldTrump⁩ above all else. The American people deserve the truth, not a sanitized version of the Mueller Report approved by the Trump Admin.”

Chairman of the House Judiciary Committee Jerrold Nadler, D – N.Y., said the panel was expected to receive a copy of the report between 11 a.m. at a news conference on Wednesday night, “well after the attorney general’s 9:30 a.m. press conference. This is wrong.”

“The attorney general appears to be waging a media campaign on behalf of President Trump, the very subject of the investigation at the heart of the Mueller report,” Nadler told reporters. “Rather than letting the facts of the report speak for themselves, the attorney general has taken unprecedented steps to spin Mueller’s nearly two-year investigation.”

Hakeem Jeffries, another member of the Judiciary Committee and the chairman of the House Democratic Caucus, accused Barr — whom Jeffries dubbed the “so-called Attorney General” of “presiding over a dog and pony show.”

Senate Minority Leader Chuck Schumer, D-N.Y., said, “The process is poisoned before the report is even released.”

“Barr shouldn’t be spinning the report at all, but it’s doubly outrageous he’s doing it before America is given a chance to read it,” Schumer added.

Late Wednesday, Nadler and four other Democratic committee chairs released a joint statement calling on Barr to cancel the Thursday morning news conference, calling it “unnecessary and inappropriate.”

“He [Barr] should let the full report speak for itself, read the statement from Nadler, Adam Schiff, D-Calif., Elijah Cummings, D-Md., Maxine Waters, D-Calif., and Eliot Engel, D-N.Y. “The Attorney General should cancel the press conference and provide the full report to Congress, as we have requested. With the Special Counsel’s fact-gathering work concluded, it is now Congress’ responsibility to assess the findings and evidence and proceed accordingly.”

The Mueller report stated that President Trump in no way colluded with Russia.
