LANSING, Mich. — Jay-Z is doing an encore for Barack Obama.
The 38-year-old rapper, a vocal supporter of the Democratic presidential candidate, is performing Saturday at a free concert in Detroit to promote voter registration. It is being offered by Obama's campaign.
Monday is the deadline in Michigan to register to vote in the November 4 election, prompting the last-minute push.
The Grammy-winning rapper, whose hits include "99 Problems," "Encore" and "Hard Knock Life," has been promoting Obama for a while, flashing his photo during concerts and telling fans that it's time for a change _ one of Obama's mottos. Jay-Z has also designed a T-shirt for sale by Obama's campaign.
Obama has said Jay-Z is one of his favorite musical artists.
