Michelle Obama's First Tweet Sent From Joining Forces Twitter Handle (VIDEO)

The tweet was sent from the twitter account for the Joining Forces initiative, which aims to improve education, health, and employment opportunities for military personnel and their families.

FLOTUS wrote, "Military families serve our nation too. Let's all show our support by #JoiningForces with them. Get involved:" Obama signed the tweet with her initials, "mo."

Mashable describes the event and writes that, after she sent her first tweet, "[t]he first lady joined with Jill Biden, the second lady of the United States, to talk about Joining Forces at — of all places — the first game of the World Series. The choice was appropriate because Game One was dedicated to veterans, service members and their families."

While a video of the tweet shows the First Lady looking rather inexperienced at Twitter, this is technically not her first foray onto the micro-blogging site. In May, at the White House Correspondents Dinner, Mrs. Obama tweeted from CNN reporter Ed Henry's iPhone, writing, "from flotus: "here at dinner this is officially my first Tweet. i am looking forward to some good laughs from the potus and jay."

At the time Ed Henry wrote that he had to get permission from White House Press Secretary Robert Gibbs and members of Obama's staff before the tweet was posted.
