Editor's Note: Ed Henry has covered the White House for CNN since March 2006. In "Henry in the House," he offers an insider's view of what it's like to cover the president.
Washington (CNN) - I'm always feeling this burst of nervous energy when I walk into the spectacular East Room for a presidential news conference. There's just been so much history in that room that it's hard not to feel the excitement of this one smaller moment in the grander sweep of White House history.
Adding to the tension is that in order to get the dozens of reporters all settled into their seats, White House aides make you file into the room at least 30 minutes before President Obama arrives. So you grab your seat and then have to sit and sit and sit and wait and wait and wait - giving you lots of time to think about two things:
1) I hope he calls on me.
2) Wait, if he does call on me, what am I going to ask?
