'He wimped out': MSNBC guest blasts Robert Mueller for failing to indict Don Jr.'s conspiracy

Special Counsel Robert Mueller's report is a devastating document for President Donald Trump and his administration, showing grossly objectionable behavior by top aides regarding Russian interference in the 2016 election and an aggressive effort by Trump himself to thwart the investigation.

But in the view of Ronald Klain, a former chief of staff to Vice President Joe Biden, Mueller didn't go nearly far enough, as he explained Thursday on MSNBC's "Deadline: White House."

"I want to disagree with the idea the Bob Mueller did a great job," he said.  "I think he wimped out here a bit."

Klain explained: "I think that the case against Don Jr. on campaign finance violations that's in the Mueller report, I think the analysis of why that's indicted wouldn't be a passing grade in a first-year election law class. I think the analysis there is incredibly weak. I think the idea that Don Jr. wasn't indicted for coordinating with WikiLeaks, for conspiring with WikiLeaks, really slides past the collusion — if you want to call it that — the conspiracy that I think this document proves out. I think there was plenty of indictable conduct with regard to both the coordination between the Trump campaign and WikiLeaks and with regard to the campaign finance violation by the Trump Tower meeting that Mueller did not press charges on, and I think that's disappointing."
