Michelle Obama has finally joined Twitter, at least in part to support her husband’s reelection campaign.

The First Lady’s first tweet (and her Obama Biden 2012-themed avatar) make it clear that the account is a part of the Obama political reelection machine.

The first tweet reads, “We’re excited today to launch @michelleobama as a new way for you to connect with First Lady Michelle Obama and the President’s campaign.”

However, the account, which is managed by the campaign staff, will also feature personal insights from Mrs. Obama herself. The from-the-First-Lady’s-own-hand messages will be signed “-mo,” just as Barack Obama’s campaign-managed account sometimes features his personally written tweets with a “-bo” signature.

In fact, Mrs. Obama has already shared something non-campaign related on her account.

“Here’s something dear to my heart: the MLK Day of Service,” reads the fifth tweet sent by the account. “Will you join me to serve your community on Monday? http://OFA.BO/NTYQkR -mo”
