House Democrats launched a concerted effort Tuesday to put their spin on Robert Mueller’s report on Russian election meddling — a day before the former special counsel will face questions about the document from lawmakers.

Speaker Nancy Pelosi condensed Mueller’s 448-page report into a six-page document that highlights the former FBI director’s most damning findings, The Hill reported. Pelosi’s office then shared copies of it with Democratic lawmakers on the Judiciary and Intelligence committees.

Titled “Exposing the Truth,” the memo was coordinated between Pelosi’s office and US Reps. Jerrold Nadler of New York, chair of the Judiciary Committee, and Adam Schiff of California, head of the Intelligence panel, the website reported.

“We’re at this incredible moment in time where we could either move forward as a unified nation in a very patriotic way to address these issues and these vulnerabilities, or our Republican colleagues will force us to turn the page … on one of the greatest threats facing our nation right now,” a Democratic leadership aide told The Hill.

“We’re hoping this will heighten the sense of urgency for a whole-of-government response to protect our democracy going forward.”

The document asserts that Mueller found clear evidence that Russia meddled in the 2016 presidential election to help President Trump and that some Trump campaign staffers welcomed the foreign assistance.

Mueller’s team of investigators also found at least 10 instances in which Trump or his allies potentially obstructed Mueller’s probe.

Pelosi’s office also launched a social-media blitz — #RetweetTheReport — featuring quotes from Mueller’s findings.

Meanwhile, the Justice Department warned Mueller not to stray beyond his report on Russian election interference when he testifies Wednesday.

In a letter sent Monday to Mueller, Associate Deputy Attorney General Bradley Weinsheimer said he should not speak about redacted material from his report — including information pertaining to pending criminal prosecutions, “uncharged third-parties” and “executive privilege,” such as “presidential communications privileges.”

The letter is entirely in line with what Mueller has already said — that he doesn’t intend to speak beyond his report’s findings.

But it gives Mueller a formal directive to point to if he faces questions he does not want to answer.

“The report is my testimony,” Mueller said in a televised statement in May.

“I would not provide information beyond that which is already public in any appearance before Congress.”

Mueller has said that indicting Trump, who repeatedly denied any collusion or obstruction and lashed out at the special counsel, was never an option because of federal rules.

Republicans on the panels plan to aggressively challenge Mueller’s more damaging findings, as well as his motives, seeking to buttress the president’s dismissal of the investigation as a “witch hunt.”

Attorney General William Barr has said congressional Democrats were trying to create a “public spectacle” by subpoenaing Mueller to testify and has offered to give Mueller an out, saying earlier this month that he and the Justice Department would support Mueller if he decided he didn’t want to “subject himself” to the congressional appearances.

Barr has also said he’d block any attempts to force members of Mueller’s team to testify before Congress.

Mueller’s testimony will include an opening statement Wednesday, but his spokesman said it would be similar in substance to his statement from late May at the Justice Department’s podium.
