Why is Fox News Attacking Obama for going to Ground Zero? Calling it " Disgusting, Offensive"?

Fox News today has been attacking the President non stop for his visit to NY Ground Zero tonight saying he's " Extrodinarily rude , Offensive, Disgusting, going to take credit". Am I missing something how is that offensive? To go and honor the 9/11 Families? He meet up with victims families of 9/11. I mean?? Am I being Naive or something what am I missing here. When Saddam Hussein went down Fox News Praised GW Bush endlessly for months about it. Bush Took lots of Credit for that. They called him a Patriot every 3 seconds. How is it offensive for Barack Obama to go there? Can someone explain to me how him visiting is offensive to anybody? My God the man 's Admin Just took Osama Bin Laden down, the guy who was being 9/11. Why Should he not be allowed to go there Seriously? He's the President, it happened under his watch. They are acting like he is going to show up in a Fighter Jet Uniform with a Banner Behind his head.
