Massachusetts Gov. Deval Patrick is in Michigan to headline a fundraiser hosted by that state's Democratic Party.
The governor will be the keynote speaker at the Jefferson-Jackson Day Dinner on Saturday.
During the event at Detroit's Cobo Hall, Patrick will speak about the life sciences initiative in Massachusetts and other political and governmental topics.
A Patrick spokesman says the governor was invited to speak by Michigan Gov. Jennifer Granholm.
Party dinners are often a stopping point for potential presidential candidates, but Patrick - who has close ties to President Barack Obama - says he's committed to seeking re-election next year.
