Michelle Obama has sent out her first tweet and, unlike the president, she also wrote it in the first person. In the video below, the First Lady is being coaxed by White House advisors to fire off her first words on Twitter in support of Military families. "So, now I just press tweet?" she asked, with an affirmative, "that's how you tweet," from her aides. The moment came and passed very quickly, and even though there was the polite applause, Michelle Obama didn't seem too excited about the milestone. Unlike, say, the Pope, who added a few exclamation points to his first tweet. She'll be signing off tweets sent by her with an "-mo."
