The subpoena comes in the wake of the Justice Department’s release of a redacted version of the Mueller report on Thursday. The redacted version was made public only after Barr gave a press conference early in the morning, in which he sought to claim that the report effectively exonerated Trump and those around him. That press conference followed an earlier statement Barr issued on March 24, in the form of a four-page letter that claimed to summarize Mueller’s findings. Critics said both his press conference and the four-page letter were part of Barr’s attempt to whitewash the Mueller report’s findings and spin the public narrative about the report before it was actually released.

In a joint statement Thursday after the report’s release, House Speaker Nancy Pelosi, D-Calif., and Senate Minority Leader Chuck Schumer, D-N.Y., charged that Barr “deliberately distorted significant portions of Special Counsel Mueller’s report.” They added that Mueller’s report “paints a disturbing picture of a president who has been weaving a web of deceit, lies and improper behavior and acting as if the law doesn’t apply to him. But if you hadn’t read the report and listened only to Mr. Barr, you wouldn’t have known any of that because Mr. Barr has been so misleading.”

Rep. Adam Schiff, the chair of the House Intelligence Committee and a California Democrat, said Thursday that Barr “did a great disservice to the country by misrepresenting significant parts of the Mueller report, by attempting to put a positive spin for the president on the special counsel’s findings.”

In the wake of the report’s release, other Democrats have called on Barr to resign, including Rep. Eric Swalwell, a California Democrat who is now running for president. Swalwell took to Twitter to attack Barr, yet another sign that Twitter has become the battlefield of choice for political combat in the Trump era.

“Russia attacked us,” Swalwell wrote on Twitter. “The #MuellerReport details a multiplicity of contacts b/w Russia & @realDonaldTrump’s team and that Trump; his team ‘materially impaired’ the investigation. Yet, OUR Attorney General acts as Trump’s defense attorney. He can’t represent both. Barr must resign.”

The differences between Barr’s statements before the report’s release and the contents of the actual report were so striking that the New York Times did a whole story comparing, side-by-side, Barr’s statements and the report.

In particular, most observers pointed to stark differences between Barr’s statements and the section in the Mueller report concerning the possibility that Trump sought to impede the Trump-Russia inquiry and thus, might be guilty of obstruction of justice. In fact, the Mueller report makes it clear that a key reason Mueller did not seek to prosecute Trump for obstruction was a longstanding Justice Department legal opinion saying that the Justice Department can’t indict a sitting president. Barr omitted that part of Mueller’s reasoning in his statements saying that Mueller hadn’t decided whether to charge Trump.

“Now that we have seen almost the entire report of more than 400 pages, we know Barr intentionally misled the American people about Mueller’s findings and his legal reasoning,” wrote Renato Mariotti, a former federal prosecutor and Politico columnist who unsuccessfully ran last year as a Democrat to be Illinois attorney general. “Mueller’s report detailed extraordinary efforts by Trump to abuse his power as president to undermine Mueller’s investigation,” Mariotti added. “The case is so detailed that it is hard to escape the conclusion that Mueller could have indicted and convicted Trump for obstruction of justice—if he were permitted to do so. And the reason he is not permitted to do so is very clear: Department of Justice policy prohibits the indictment of a sitting president.”

Barr’s statements prior to the release of the report were also misleading when it came to the issues of Trump and Russian interference in the election.

Barr’s statements prior to the release of the report, however, were also misleading when it came to the issues of Trump and Russian interference in the election. Barr discussed but did not linger on the portion of the report about the Russian cyberattacks against Hillary Clinton’s campaign — attacks that were designed to help Trump win the election. And Barr was disingenuous in the way he sought to cut and parse Mueller’s report to make Trump look better on issues related to contacts and links between the Trump campaign and Russia.

The New York Times notes, among a number of examples, that in his March 24 letter, Barr lifted an exculpatory section of a sentence from the Mueller report while omitting the more damaging first part of the same sentence. Here is a paragraph from the Mueller report, with the portion of one sentence released by Barr in bold:

The [Russian] social media campaign and the [Russian intelligence] hacking operations coincided with a series of contacts between Trump Campaign officials and individuals with ties to the Russian government. [Mueller’s] Office investigated whether those contacts reflected or resulted in the Campaign conspiring or coordinating with Russia in its election-interference activities. Although the investigation established that the Russian government perceived it would benefit from a Trump presidency and worked to secure that outcome, and that the Campaign expected it would benefit electorally from information stolen and released through Russian efforts, the investigation did not establish that members of the Trump Campaign conspired with the Russian government in its election interference activities.

In fact, the Mueller report’s findings on contacts between the Trump circle and Russia are extensive and damning. The report does not exonerate Trump or his campaign; instead, Mueller says he didn’t have enough evidence to bring criminal charges for conspiring with the Russians. The report states that “while the investigation identified numerous links between individuals with ties to the Russian government and individuals associated with the Trump Campaign, the evidence was not sufficient to support criminal charges. Among other things, the evidence was not sufficient to charge any Campaign official as an unregistered agent of the Russian government or other Russian principal.”

“Further,” the report adds, “the evidence was not sufficient to charge that any member of the Trump Campaign conspired with representatives of the Russian government to interfere in the 2016 election.” But went on to say that the “investigation established that several individuals affiliated with the Trump Campaign lied to [Mueller’s team] and to Congress, about their interactions with Russian-affiliated individuals and related matters. Those lies materially impaired the investigation of Russian election interference.”
