On Sunday evening, Barr released a four-page summary of Mueller's findings regarding election interference in the 2016 election and possible obstruction of justice committed by President Donald Trump
Attorney General Barrs letter raises as many questions as it answers," they wrote . "The fact that Special Counsel Muellers report does not exonerate the president on a charge as serious as obstruction of justice demonstrates how urgent it is that the full report and underlying documentation be made public without any further delay."
Barr's summary said that while Mueller did not "draw a conclusion one way or the other as to whether the examined conduct constitutes obstruction," Mueller's report "also does not exonerate" Trump of any criminal conduct.
Barr continued that he and Deputy Attorney General Rod Rosenstein who oversaw the Mueller probe for most of its duration concluded that the special counsel's findings were "not sufficient" to determine that Trump committed obstruction of justice.
"Given Mr. Barrs public record of bias against the Special Counsels inquiry, he is not a neutral observer and is not in a position to make objective determinations about the report," Schumer and Pelosi charged in their statement.
Barr is coming under scrutiny from Democrats in Congress for his and Rosenstein's conclusion that Trump did not commit obstruction of justice in light of a memo he wrote before his appointment as Attorney General questioning the legality of Mueller's obstruction probe.
The memo called Mueller's inquiry into whether Trump obstructed justice when he fired former FBI director James Comey in the spring of 2017 "legally unsupportable" and "potentially disastrous."
