AUDIE CORNISH, HOST:

Last year's killing of Osama bin Laden has become a distant campaign talking point here in the U.S. But in Pakistan, the issue is still burning. And Defense Secretary Leon Panetta stoked the fire recently by confirming that a local Pakistani doctor, Shakil Afridi, had helped the CIA find bin Laden.

Panetta told the CBS program "60 Minutes" that he is very concerned about Afridi's well-being because the doctor was detained by Pakistan after the bin Laden raid, and may well be tried for treason.
