Whoa there. Give the man a break. His son was brutally murdered a year ago by some white hispanic who was just wrongfully acquitted of the crime. On top of all that, during his administration he's had to deal with obstructionist opposition from the GOP even through he had a supermajority in Congress, has had to do endless fundraisers, been forced to golf scores of rounds AND has been forced to explain things to the one or two simpletons in this country who will not blindly accept his Bob the Builder inspired campaign slogans as a vision for a utopian future.
The man simply does not have time to deal with pesky journalists asking irrelevant questions about minor incidents that don't really matter. He's all about going FORWARD!, rather than focusing on the past, which is the past.
