"The President said the position of Attorney General was his most important appointment and that Sessions had 'let [him] down, '" comparing him to Barack Obama's Attorney General Eric Holder and Robert Kennedy, the attorney general for and brother of John F. Kennedy.
Sessions said he wished to remain attorney general, but said it was up to Trump, the report said.
The criticism stands in stark contrast to the attorney general's declaration on Thursday that the White House had "fully cooperated" with the investigation.
House Speaker Nancy Pelosi, D-Calif., said Barr had "thrown out his credibility & the DOJ's independence with his single-minded effort to protect" Trump.
"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 said.
The release marks a watershed moment in Trump's presidency, promising new details about some of the biggest questions in the probe, including the extent and nature of his campaign's contacts with Russian Federation and actions Trump may have taken to hinder the inquiry including his 2017 firing of FBI Director James Comey.
Mueller's report Thursday described several actions by President Donald Trump which his critics could interpret as attempts to interfere with the investigation. He says, "You'll see a lot of very strong things come out tomorrow". Two days later, Barr sent lawmakers a four-page letter saying the inquiry did not establish that Trump's 2016 campaign team engaged in a criminal conspiracy with Russian Federation and that Mueller had not exonerated Trump of committing the crime of obstruction of justice.

While the president has claimed that the almost 400-page report "totally" exonerated him, Democrats aren't buying it and plan to seek an unredacted copy of Mueller's report, the culmination of a 23-month investigation.
Special Counsel Robert Mueller's long-awaited report on Russia's role in the 2016 United States election will be released on Thursday, providing the first public look at the findings of an inquiry that has cast a shadow over Donald Trump's presidency.
After almost two years of waiting, America will get some answers straight from Robert Mueller.
In a report appendix, the special counsel wrote that his office sought an interview with Trump for more than a year, beginning in December 2017, and considered an interview "vital to our investigation".
