According to Citizens for Legitimate Government, Louisiana Sen. David Vitter has checked into Ochsner Foundation Hospital. Ochsner is not a pscyhiatric facility, but since Katrina, most such facilities have closed. Ochsner does have a department of psychiatry, though. Or perhaps he is just there for a stress check.
Vitter's spokespeople say that he is planning to return to work next week. He is described as being "in seclusion."
