On April 10, in a back and forth between Barr and Sen. Chris Van Hollen over Barr's March 24 letter, the Maryland Democrat asked Barr, "Did Bob Mueller support your conclusion?"
"I don't know whether Bob Mueller supported my conclusion," Barr replied.
Even when narrowly taken, Barr's answer stretches credulity. In his letter, Mueller specifically says that Barr's summary laying out the bottom-line conclusions of the report "did not fully capture the context, nature, and substance of this Office's work and conclusions." From this, it appears Mueller was not satisfied with Barr's conclusions.
More broadly, Mueller also expressed concern that Barr's summary created "public confusion about critical aspects of the results of our investigation" which "threatens to undermine a central purpose for which the Department appointed the Special Counsel."
On Tuesday night, after news broke of the Mueller letter, Van Hollen lashed out. "We now know Mueller stated his concerns on March 27th," Van Hollen
tweeted, "and that Barr totally misled me, the Congress, and the public. He must resign."
