He unleashed a series of tweets Monday focusing on the previously released summary of special counsel Robert Mueller's conclusions - including a crucial one on obstruction of justice that Trump again misrepresented - produced by Attorney General William Barr.
But the sprawling nature of the 22-month investigation is fueling concerns.
"They got asked questions and told the truth and now they're anxious the wrath will follow", one former White House official said. "You put hundreds of witnesses under oath and you throw all these subpoenas around - if there's nothing controversial or embarrassing that's disclosed, that would be kind of surprising". No Trump supporters are going to read the full report, the state-run media will claim, since there is nothing new, that therefore Trump has been vindicated, and the rest of the public, even those who may see through the charade, already exhausted from this two-year saga, will quickly lose interest, especially with the focus now turning to the 2020 election. Needless to say, if the "truth" entirely consisted of nothing-to-see-here reminiscences, no one would be anxious about having their name attached to them.
Portions of the report being released by the Justice Department will be redacted to protect grand jury material, sensitive intelligence, matters that could affect ongoing investigations and damage to the privacy rights of third parties, the attorney general has said.
Indeed, all of Washington will be studying the report.
Democrats have noted that the Justice Department has released such information before, including some related to Mr Mueller's own investigation while it was in progress. The department has refused to offer any solace.
But less than 48 hours before one of the most anticipated Washington reports in decades becomes public, the White House has yet to go into crisis mode.
Mr. Trump, meanwhile, has maintained a consistent line. And the reality is that it doesn't take 400 pages to say no collusion no obstruction. He's called it a "witch hunt" more times than we can count. BookMaker.eu put the over-under at 1.5 times. So I think, I think Thursday's going to be a day where you'll see the Democrats making a lot of molehills into mountains.
Jerrold Nadler, has said he is prepared to issue subpoenas "very quickly" for the full report on Russian Federation and Donald Trump's presidential campaign if it is released with blacked-out sections.
"It just may be a bad news cycle", the source said. Some of those who cooperated with Mueller's probe are questioning whether their names will be redacted or whether the information in the report points directly at them as a source.
Barr has offered to testify about the report in early May. The president's attorneys have promised such a rebuttal to Mueller's almost 400 page report for months. But some Republicans defending Barr are also citing precedent, saying it is appropriate to keep at least some of the information from Congress and the public. President Trump said he has moved on, insisting that the report exonerated him.
Mr. Trump, meanwhile, is trying to keep the public focused on Mr. Mueller's bigger conclusion that there was no criminal conspiracy with Russian Federation - undercutting the narrative that launched the lengthy investigation. The president himself seethed at a political rally that the whole thing was an attempt "to tear up the fabric of our great democracy". "If the Mainstream Media were honest, which they are not, this story would be bigger and more important than Watergate".
"It does make it hard for Democrats to make clear to the public what the president did that did constitute abuse of power".
"It will surely be worse news for the president than the summary letter from the attorney general", said Marc Hetherington, a political science professor at the University of North Carolina.
