The first lady says on Twitter that she dropped her absentee ballot in the mail Monday, telling her followers: "I couldn't wait for Election Day."
The president replied in a tweet that he intends to vote early in person in his home state of Illinois on Oct. 25 - three days after the final presidential debate.
Obama's campaign says it's the first time a presidential nominee and his spouse will not vote in person on Election Day. It shows how Obama's campaign is trying to take advantage of early voting going on in several key battleground states.
Obama plans to discuss early voting in Ohio and Iowa on Wednesday, after Tuesday's second presidential debate.
