Official White House Photo by Pete Souza.
The White House is out with its latest gallery of official photos, including this one from Dec. 14 showing counterterrorism chief John Brennan briefing President Obama on the details of the mass shooting at Sandy Hook Elementary in Newtown, Conn. The president went on to hold a tearful news conference that afternoon and would later call that day the "worst" of his presidency.
