Investigators on a GOP-led commission in Michigan dismantled a series of conspiracy theories related to the 2020 presidential election, delivering a stunning intra-party rebuke to former President Donald Trump and his Stop the Steal allies.

“There is no evidence presented at this time to prove either significant acts of fraud or that an organized, wide-scale effort to commit fraudulent activity was perpetrated in order to subvert the will of Michigan voters,” the Michigan Senate Oversight Committee, which is controlled by Republicans, said in a 55-page report.

“After innumerable hours over many months, watching, listening, and reading both in-person testimony and various other accounts, I am confident in asserting that the results of the November 2020 General Election in Michigan were accurately represented by the certified and audited results,” said Republican state Sen. McBroom, who chaired the committee, in a statement.

The committee heard testimony from 87 eyewitnesses, experts, and citizens, reviewed over 400 pages of testimony, and subpoenaed key documents from the secretary of state.

CNN provides details on the findings:

The Senate committee, led by Republicans, debunked claims that deceased people or non-residents voted in the election, voting tabulators were compromised, ballots were harvested, ballots were “dumped” at the TCF Center in Detroit, and votes for Trump in Antrim County were switched.

The report explicitly name checks Mike Lindell, the MyPillow CEO turned Trump diehard. Lindell claims foreign and domestic actors hacked Michigan’s voting machines. The report dismisses that assertion, saying “this narrative is ignorant of multiple levels of the actual election process.”

“The Committee strongly recommends citizens use a critical eye and ear toward those who have pushed demonstrably false theories for their own personal gain,” the report concludes.

The report also excoriates the conspiracy theory that Dominion Voting Systems manipulated ballots. “Further, the Committee is appalled at what can only be deduced as a willful ignorance or avoidance of this proof perpetuated by some leading such speculation,” the report said.

While the report deals a blow to Trump’s delusions of having the 2020 election overturned, it does recommend that absentee voting, a priority for Democrats, should be curbed.

More from CNN:

While it found no evidence of widespread fraud, the committee said there are “glaring issues” and “clear weaknesses” in Michigan’s elections system “that require legislative remedy.”In its report, the committee recommended that the secretary of state cease mailing out unsolicited absentee ballot applications, signature verification requirements be established, and video security be added to ballot drop boxes, among other suggestions.
