The Oath: President Obama, VP Biden Officially Sworn Back Into Office It’s official … President Obama is president again. Four more years. AP Photo/Larry Downing, Pool Sasha and Malia were psyched, and FLOTUS was proud: Barack just took the official oath at the @whitehouse & used my grandma’s bible for the ceremony. I’m so proud of him. –mo — FLOTUS (@FLOTUS) January 20, 2013 Vice President Joe Biden was also sworn in today. Supreme Court Justice Sonia Sotomayor did the honors in front of 120 guests (BIDEN NEEDS AN AUDIENCE — ALWAYS!) in the VP’s official residence at the U.S. Naval Observatory. Biden personally selected Sotomayor. AP Photo/Carolyn Kaster No Mitt Romney photos have surfaced yet today.
