Bill Barr destroyed himself... He ruined himself when asked for a transcript of his phone call with Mueller, and he simply said no. It's Congress's job to investigate wrong doings. They hold the check of the Executive Branch which includes AG Barr.
If the conversation wouldn't hurt Barr or Trump... why would he NOT share that? It was on speaker phone, it's not like it was some serious national security info.
Redacted or personal items are not public domain. The Democrats make everything that should not be repeated cast in the worst light for President Trump and his staff. It would be like the brain trust in a platoon of defenders putting himself on the firing line and taking a lethal hit for weaker members who could not thereafter defend themselves due to lack of knowledge or experience. IOW, if the American people would suffer because a dedicated jurist of the best kind failed to care about the leadership in America, it would be unthinkable to William Barr. He will defend the Constitution and the Executive Branch from an entire party of communists dedicated to the decimation of the Constitution, the President, and to the disenfranchising of American voters who put President Trump in office to lead them out of the Obama morass that most of America literally hated, but were not allowed to call blacks on the carpet for the flagrant hatred Obama had for 7/8ths of the people of the United States who hate communism with a purple passion due to its propensity to murder people who disagree mits der Furor. They viewed the White House as an unsafe storage house of Muslim hatred due to Obama's love affair with loose cannon Louis Farrakhan and his scary bunch of AK-47 armed haters of
all other Americans.
You've been listening to too many little fibbies arranged to pillory the very people who defend America from people like the hateful Mr. Farrakhan and his multitude of over-armed, disrespectful bullies.
