Why is McCain getting $58,000 a year in disability income?

Kudos to John Aravosis from Americablog for asking this question. Why is he getting $58,000 a year in disability income? I drew disability for 10 years straight, and when I went back to work two years ago, my disability stopped after nine months of work. So how is it that John McCain can work as a Senator and still draw $58,000 a year?

As John pointed out, this is the same John McCain that thinks the new GI bill in congress is too generous to the troops. Really John? Don't you think your $58,000 is too generous?
