This has got to be a matter of national security. An ogre known for beheading its foes was allowed to be in the same room as the President of the United States.
We can assume Khloe Kardashian was on a leash, or tethered to her chair in some other amusing fashion, on her White House meeting with Barack Obama. I don’t remember hearing / reading any reports about Obama being attacked by a rabid reality star and hence minus one leg. NFL, NBA, MLB, NHL and several college sports teams met with Obama following their assorted wins. Some bright spark decided it would be a good idea to let the gaggle of light-headed WAGS (wives and girlfriends) attend the meeting. Lamar Odom, and his Los Angeles Lakers teammates did a meet-and-greet with the President, in Washington, on Monday. The Pres. fearlessly took a dive headfirst into the gaggle of seated, vapid wives and be-jewelled swamp creatures. After the team posed for a photo, Kobe Bryant presented the big guy with an Obama #1 Lakers jersey.

Its just a guess, but she was probably there to assist Obama with some kind of plan of attack against Kim’s ass for when it finally gets to big and explodes. Just think about it, we could all be in grave danger!
AGREED – we must hide!
[...] Obama allows Ogre Kardashian into White House. (AG) [...]
For ultimate safety I suggest going underground
