The president happened to send his first ever 'tweet' when he along with the First Lady visited the office of Red Cross in Washington, which is serving as disaster operations centre to coordinate humanitarian aid to quake-hit Haiti.
After appreciating and applauding the members of the Red Cross for the 'great work', the president stopped at the social media team desk and hit the 'Send' button on a message just typed on Twitter.
“President Obama and the First Lady are here visiting our disaster operation centre right now," the tweet said.
The first tweet was followed by, “President Obama pushed the button on the last tweet. It was his first ever tweet!"
While addressing the press pool, president Obama spoke about the money raised through Twitter.
“I was just told that, just by Twitter, we"ve seen $ 21 million raised already, which just shows how generous the American people are in times of need," he said.
