Yeah, Let's Waste More Money

More and more, I think the Obama's are going to divorce or have a loveless marriage like the Clintons.
From Fox News: A man jumped over the fence of the White House on Friday and made it through the front door before officers managed to apprehend him, the Secret Service said. President Obama had departed the White House just minutes earlier....
The incident occurred shortly after 7 p.m., only minutes after Obama and his daughters, along with a guest of one of the girls, left the White House aboard Marine One on their way to Camp David, the presidential retreat in Maryland where Obama and his family were to spend the weekend. First lady Michelle Obama had traveled separately to Camp David and was not at home.  http://www.foxnews.com/politics/2014/09/20/white-house-fence-jumper-sparks-evacuation/
Ok, why did she have to travel separately to Camp David?
And what about the extra carbon footprints this incident has caused?
