Because the info is dubious because it comes from officials in the Justice Department and sounds a lot like something Barr himself would say happened. The Trump defenders are excising this little bit of skeptical info and running with it.

The Washington Post are the ones who originally cited the Justice Department officials's comments in regards to the call I mentioned. So I think we can safely say that the call happened. If it didn't happen, then that's something that should be looked into.

Big logick.

Nice try FBI.

^ Yes, Mueller was sufficiently angry to write two letters, to be put on record, explaining that Barr was mis-handling the release of his report. So far, there is little more than Barr's word that Mueller later back-peddled his criticisms in a later convesation.
Also, Barr's denial of knowing that Mueller was unhappy is only one of six false or evasive statements from Barr in yesterday's testimony:-

To that list of six, I'd add one more as well:

There is also the question about "Did Trump ask for Mueller to be fired?" Barr went into a weedling distinction about the difference between "firing someone" and "asking someone to be removed." Barr claimed that Trump only wanted the latter - even though in Mueller's report, the word used (something like 5 times) is "fired." It's one thing for the supposedly-impartial AG to give Trump the benefit of the doubt, but it is another thing when the AG invents a doubt that is not textually there, and then gives Trump the benefit of that too.
Bottom Line: Barr is a lying partisan charlatan who has betrayed his office, his integrity and the Justice Department all for the sake of placing Trump above the reach of the law.

If Trump said "let's bomb France because their bread sucks" and the generals were like "nah", should Trump be charged with a war crime?

You might find this article rather interesting. Provides more of a nuanced background to Barr's conduct.

Mueller is a nut sucking cowardly bitch. It was his job to press charges. He brings everyone up on charges except for the gang boss and now he wants to cry about the milk he ****ing spilt. Mueller was tasked with a man’s job but he was a scared little boy.

Anyway - it’s over now - Trump won on all collusion and obstruction stuff - thanks to Mueller who gave him a pass.

Yup. No room for nuance in Trump World. He won and his base is flat out ecstatic.

William Barr Keeps Lying About Mueller, and People Keep Trusting Him Anyway

"The Post’s account summarizes a phone call between Mueller and Barr. It reads an awful lot like Barr’s side of the story...":
