Nor did his report confirm Trump committed any "crimes".
'''
On March 22, 2019, Mueller concluded his investigation and submitted the special counsel's final report to Attorney General
William Barr.
[107] A senior Department of Justice official said that the report did not recommend any new indictments.
[7] On March 24, Attorney General Barr submitted a summary of findings to the
United States Congress. He stated in
his letter, "The Special Counsel's investigation did not find that the Trump campaign or anyone associated with it conspired or coordinated with Russian in its efforts to influence the 2016 U.S. presidential election." Mueller's report also reportedly did not take a stance on whether or not Trump committed obstruction of justice; Barr quoted Mueller as saying "while this report does not conclude that the President committed a crime, it also does not exonerate him."

Basically Mueller et al couldn't find one way or another. Underscores the kangaroo court the whole fraud and sham investigation was.
I suggest you look harder to see where you lost your brain.
