Blood-alcohol test results determined Michael Brodkorb was intoxicated the night his car crashed into a wall on I-35E in Mendota Heights.
The Bureau of Criminal Apprehension found that the Eagan resident had an alcohol concentration of 0.10, which is above the legal limit of 0.08.
Brodkorb, 39, was driving a 2004 Subaru Forester northbound on I-35E on Jan. 23 when it hit the wall at the walkway and came to rest against the jersey barrier, according to the State Patrol report.
The road condition on the three-lane northbound section was described as dry at the time of incident.
Brodkorb was seriously injured in the crash and spent several days at Regions Hospital in St. Paul.
Brodkorb has been at the center of attention after admitting to an affair he had with former Senate Majority Leader Amy Koch, R-Buffalo, when he was her executive assistant.
He lost his job in December 2011, one day after Koch resigned her leadership position over an “inappropriate relationship” with a staffer.
Last July, Brodkorb filed a lawsuit against the Senate, the state of Minnesota and Secretary of the Senate Cal Ludeman claiming gender discrimination. He claims he was treated differently than female staffers who had affairs with male legislators.
The lawsuit, which is pending, is seeking damages in excess of $500,000.
