Mr. Cheney also received a great deal of mail from people all over the country during his time at Inova Fairfax Hospital.

Ahern tells Fox News, the former Vice President has been calling people he doesn't know personally, "perfect strangers", who have sent in cards and notes wishing him well. Ahern says, "most of them are shocked when he [Cheney] tells them who is calling."

According to Ahern, Mr. Cheney and his family are very appreciative of all of the well wishes and prayers.
