ST. PAUL, Minn. — A Minnesota state senator who was caught in a sting operation resigned under fire Thursday after he was charged with soliciting a minor for prostitution.

Republican Justin Eichorn, of Grand Rapids, submitted his resignation in a letter to Gov. Tim Walz, Senate Minority Leader Mark Johnson said in a statement.

“This is the right thing to do for his family and the Senate,” Johnson said. “We are ready to move on and do the important work that needs to be done at the Capitol.”
