Michigan Attorney General Bill Schuette is expected to make a major announcement Wednesday morning.
Many believe Schuette, the Republican nominee for governor, will reveal his choice for lieutenant governor.
He will be in Grand Rapids at 9 a.m., Lansing at 12:15 p.m. and Bloomfield Hills at 2:45 p.m.
Democratic nominee Gretchen Whitmer and Libertarian nominee Bill Gelineau have not yet announced running mates.
