Mueller report PSA: Prepare for disappointment

That’s the word POLITICO got from defense lawyers working on the Russia probe and more than 15 former government officials with investigation experience spanning Watergate to the 2016 election case. The public, they say, shouldn’t expect a comprehensive and presidency-wrecking account of Kremlin meddling and alleged obstruction of justice by Trump — not to mention an explanation of the myriad subplots that have bedeviled lawmakers, journalists and amateur Mueller sleuths.

Perhaps most unsatisfying: Mueller’s findings may never even see the light of day.

“That’s just the way this works,” said John Q. Barrett, a former associate counsel who worked under independent counsel Lawrence Walsh during the Reagan-era investigation into secret U.S. arms sales to Iran. “Mueller is a criminal investigator. He’s not government oversight, and he’s not a historian.”
