Mitch McConnell's health episodes draw attention to obscure, but influential Capitol Hill doctor

"In my case, it saved my life," Rep. Dan Kildee, Democrat of Michigan, recalled. Kildee emphasized the word "saved."

Kildee was sufficiently uncomfortable and concerned earlier this year to call for an appointment at Congress' Office of the Attending Physician, a nondescript suite on the first floor of the Capitol.

"It allowed me to have something relatively routine checked out," Kildee told CBS News, rather than waiting to see his own doctor at home, in Michigan.
