The James S. Brady Press Briefing Room is a small theater in the West Wing of the White House where the White House Press Secretary gives briefings to the news media and the President of the United States sometimes addresses the press and the nation.
 It is located between the workspace assigned to the White House press corps and the office of the Press Secretary.
The White House Office of the Press Secretary, or the Press Office, is responsible for gathering and disseminating information to three principal groups: the President, the White House staff, and the media.

Eric Schultz is a senior advisor to former President Barack Obama and is the founder of Schultz Group.

 After White House Deputy Press Secretary Josh Earnest replaced Jay Carney to become White House Press Secretary, Schultz was appointed White House Deputy Press Secretary.
 In this role, Schultz often diffuses "tensions with humor.
 But he can be relentless in pushing his message in both public and private conversations.”
 Former White House Communications Director Jen Psaki compared Schultz to fictional crisis manager Olivia Pope, "he's the person you want next to you in a foxhole when there's a crisis."
 At the end of President Obama's second term, former White House Senior Advisor Valerie Jarrett said of Schultz, “We’ve all grown to rely on his wise counsel" and that the President "trusts his sound judgement."

 He handled embarrassing episodes, such as those related to the Soviet downing of an American spy plane, the U-2 in 1960.
 He handled press relations on Eisenhower's international trips, sometimes taking the blame from a hostile foreign press.
 Eisenhower often relied upon him for advice about public opinion, and how to phrase complex issues.
 Hagerty had a reputation for supporting civil rights initiatives.
