Reading the end of the report, Barr completely ignored the following conclusions from Mueller's report (this is directly taken verbatim) and CNN was not bull shitting about this:

"The evidence we obtained about the President's actions and intent presents difficult issues that would need to be resolved if we were making a traditional prosecutorial judgment.

At the same time, if we had confidence after a thorough investigation of the facts that the President clearly did not commit obstruction of justice, we would so state."

Basically, the President is saying "neener neener!!! I didn't give you enough evidence!!! You can't do NOTHING!!!! NEENER NEENER NEENER!!!"
