Gov. Rick Snyder is running for re-election.
News 10 received an email from his campaign Thursday night saying the official announcement will happen Monday morning in Detroit, with events in Lansing and Grand Rapids to follow.
The Lansing stop will be at the headquarters of Two Men and a Truck on Belle Chase Way, near the corner of Pine Tree and Jolly roads.
The governor refused to answer questions about a re-election bid for months, but had been raising money all along.
His staff said earlier this week, he has around $4 million in the bank.
