As noted by Washington Post reporter David Nakamura, newly-minted Obama White House press spokesman Josh Earnest managed to anger the White House press corps right out of the gate.
 
While it may not seem like a big deal that press can be "testy" with a White House, consider the contrast at the beginning of the Obama Presidency in 2009.  Traditionally, the White House press corps does not stand when a president enters the briefing room, a measure of respect for their colleagues operating TV cameras in the rear of the small room.  However, the White House press corps was so enamored with the former community organizer, they broke protocol and many stood as Obama entered the White House press briefing room.
