She faked the other injury. At best, she might have bumped her head slightly and turned that into a huge major medical emergency. Her blood clot, may be pre-existing or could be a "blood clot" wink wink. I had a friend whose mother tried to kill herself. But back then she was able to be admitted into the hospital for another reason. They gave the name of some disease so that no one would know she tried to harm herself and the family didn't have the stigma. Likewise, for all we know Hitlary might have some anxiety, some worry, some severe stress and she was admitted for a "blood clot". Who knows. Either way, this just works out perfectly for her and Obama. The coincidence that she not have to face an inquiry over Bengahzi plus not ruin any possible presidential run in the future (even though she will be well past her expiration date in 2016- who wants an old prune running the county).
I say that once she recovers and thinks Benghazi blows over... she should get a subpena forcing her to face the Benghazi investigators. No mercy, get her in there and make her talk. No matter how many "injuries" she may have.
