White House Releases President Obama's Second Official Portrait [PHOTOS]

The White House has released President Obama’s official portrait for his second term.

Taken by official White House photographer Pete Souza, the photo is much more casual than the president's first portrait. In the new portrait, Obama sits in the Oval Office, smiling with his arms folded, as opposed to his 2009 portrait that shows a straightfaced Obama in front on of a simple back drop and the American flag.

The new portrait will replace the one taken in 2009, and it will hang in all federal buildings.

The 2009 portrait is notably the first presidential photo to not be painted, but rather taken with a digital camera. Souza, then-newly appointed as the official White House photographer, snapped the shot with a Canon EOS 5D Mark II.

A painted version of the portrait is apparently in the works and is expected to be completed by the end of Obama's tenure as president.

Several news sources have noted that Obama has visibly aged since his first official photo. The fact has hardly gone unnoticed by the Commander in Chief.

At the 2012 White House Correspondent’s dinner, Obama joked about his aging progression, showcasing a series photographs. One from the beginning of his first term as president, one nearing the end of his first term, and one suggesting that he would miraculously age into Morgan Freeman.

"That's not even funny," the president said during his address.

Obama’s first official portrait was as a senator, and the outdoor shot features a much younger, smiling Obama; his newest official portrait is particularly reminiscent of this photo taken many years ago.

Obama's second term begins at noon EST on Sunday.
