PEPFAR -- The President's Emergency Plan For AIDS Relief.

The multi-billion-dollar government initiative to address the global HIV/AIDS epidemic turns 20 years old this week – President Bush signed PEPFAR into law on May 27, 2003.

When it was proposed and implemented 20 years ago, PEPFAR was the largest commitment by any nation to combat a single disease in human history.

Now, to mark PEPFAR's 20th anniversary, we hear directly from the politicians involved in the program -- and the bipartisan tone the initiative set for Washington and for President Bush -- as C-SPAN's podcast "The Weekly" presents a special episode: PEPFAR: An Oral History.
