WaPo:

One year ago this month, Wisconsin State Assembly Speaker Robin Vos (R) sat on a private plane with Donald Trump and updatedthe former president on the investigation he had launched into the 2020 election, even though there was no evidence of widespread fraud.

Since then, Trump has repeatedly pressured Vos — privately and publicly — to find a way to overturn the election results, which the state lawmaker has said is impossible and illegal. Wisconsin’s 2020 results still stand, showing that Joe Biden won Wisconsin by more than 20,000 votes.

The alliance between the two came to a clear end on Friday night as Trump held a rally in the Milwaukee suburbs and urged his supporters to vote for Vos’s challenger, Adam Steen, in Tuesday’s primary.

“Adam Steen is running to defeat your RINO speaker of the house Robin Vos,” Trump said, using the acronym for “Republican in name only.” “Despite undeniable evidence of rigging and fraud, Speaker Vos has taken no steps to hold the Wisconsin Elections Commission accountable, clean up the voter rolls or right any of the other terrible wrongs.”

Despite the president’s assertion about voting irregularities, a nonpartisan legislative audit and review by a conservative group found no evidence of significant electoral fraud in the state.
