Republican candidate for governor Tim Michels has spent more than $7.9 million of his own money on his campaign.
The reports detail what has largely been a self-funded campaign for Michels, who has been endorsed by Donald Trump.
The millionaire co-owner of a Brownsville-based construction company has received about $60,000 in individual donations since entering the race in April.
Michels is going head-to-head on financing with fellow Republican gubernatorial candidate and former Lt. Gov. Rebecca Kleefisch,
She has raised more than $3.6 million in the first half of the year and about $7 million total since entering the race in September.
The winner of the Aug. 9 primary will go on to face Democratic Gov. Tony Evers, who is seeking a second term.
