Now on Twitter: Michelle Obama

WASHINGTON -- Michelle Obama went live on Twitter yesterday, and scooped up more than 88,000 followers within a few hours.

In her first tweet, the first lady writes: "Hi, everyone, and thanks for the warm welcome. Look forward to staying in touch with you here. -mo."

Her Twitter feed will be managed by the President Barack Obama's re-election campaign, with any tweets from the first lady herself to be signed "-mo." The first two tweets came from the campaign staff, and described the account as "a new way for you to connect with First Lady Michelle Obama and the President's campaign." The third came from the first lady herself.

The president also has a Twitter account managed by the campaign.
