Ken Starr said Special Counsel Robert Mueller "punted" by declining to reach a conclusion on whether President Trump or his associates obstructed justice.

Attorney General William Barr on Sunday released the "principal conclusions" of Mueller's completed Russia probe in a four-page letter to lawmakers, which stated definitively that Mueller did not establish evidence that Trump's team or any associates of the Trump campaign had conspired with Russia to sway the 2016 election.

According to Barr's letter, however, Mueller's report did not reach a conclusion on whether Trump obstructed justice, and left that decision to Barr and officials at the DOJ -- who determined there was insufficient evidence of obstruction.

On "Outnumbered Overtime" Monday, Starr, a former independent counsel whose investigation into Whitewater led to President Bill Clinton’s impeachment hearings, said he does not believe it was "wise" or "courageous" for Mueller to leave that decision to the attorney general.

"Apparently this was known -- from some of the reporting I've seen -- several weeks ago, that for whatever reason Bob Mueller was not going to come to rest on the one hand and on the other hand," Starr said.

Despite that, Starr said he has "great confidence" in Barr, whom he noted consulted Deputy Attorney General Rod Rosenstein in reviewing the Mueller report.

"They consulted with department officials, they reviewed the evidence -- apparently they had several weeks to review this -- and under the settled practices and principles of federal prosecution, there is no basis for prosecuting anyone," Starr said.

"Now, that is a clean bill of health from the Justice Department, which I think is a bill of health with integrity."
