Obama Victory Tweet Sets All-Time Record

The words "four more years", coupled with a photo of Barack and Michelle Obama embraced in a hug, have become the most retweeted Twitter post in history.

The US president tweeted the message at 04:16 am GMT, and it has since been retweeted over half a million times, BBC informs.

Barack Obama also thanked his supporters, posting: "This happened because of you. Thank you." That tweet has been retweeted 170,000 times, pushing it to third on the all-time list.
