President Obama may have won a second term last night, but he also got a new feather in his cap. His victory tweet became the most-retweeted message from his account.

Twitter confirmed that Obama’s tweet — which read “Four more years” and featured a picture of him and Michelle Obama embracing — earned more retweets than any other message from his account.

As of 11:30 a.m. Wednesday, the message had been shared more than 670,000 times and counting.

Those numbers may even give Obama the title for most-retweeted message of all time. By MediaBistro’s Shea Bennett’s reckoning, the victory tweet far outstrips a message from Justin Bieber that had around 223,000 retweets and previously held the list’s top spot. Twitter did not confirm those numbers.

Other election night Obama tweets that lit up the Twittersphere included another victory message, “This happened because of you,” which pulled in more than 240,000 retweets. A message signed by Obama personally also earned more than 100,000 retweets — 158,000 just after 11:30 a.m. on Wednesday.

Meanwhile, the same photo of the embracing Obamas grabbed 3.3 million likes, 422,000 shares and nearly 160,000 comments on Facebook. According to a Facebook post on the company’s site for journalists, the photo is the most-liked post of all time.

Twitter also reported that its users sent out 31 million election tweets throughout the day Tuesday. Traffic on the network peaked when news organizations called the election for Obama, sending 327,452 tweets per minute at 11:19 p.m. That, the company said, made it easily the most tweeted moment of the entire election.

To quote Twitter chief executive Dick Costolo’s Tuesday night message, “Wow. The tweets they are many. Incredible.”

So, now that Obama has broken a social media record or two, what’s next on his — or his social media team’s — list?

One suggestion: Check in on Foursquare a few more times to become mayor of the White House. Seriously.
