The investigation led by Robert S. Mueller III found that neither President Trump nor any of his aides conspired or coordinated with the Russian government’s 2016 election interference, according to a summary of the special counsel’s findings made public on Sunday by Attorney General William P. Barr.

The summary also said that the special counsel’s team lacked sufficient evidence to establish that President Trump illegally obstructed justice, but added that Mr. Mueller’s team stopped short of exonerating Mr. Trump.

“While this report does not conclude that the president committed a crime, it also does not exonerate him,” Mr. Barr quoted Mr. Mueller as writing.
