Bill Frist told George Stephanopoulos that 15% of condoms fail which is false.

From the Waxman Report:

When used properly and consistently, condoms fail to prevent pregnancy and sexually transmitted diseases (STDs) less than 3 percent of the time, federal researchers say, and it is not known how many gay teenagers are HIV-positive.

It took George repeatedly asking Frist if sweat and tears caused the spread of HIV.

George: You're a doctor. Do you think tears and sweat can transmit HIV"

Frist; I don't know...I can tell you..

George: You don't know?

Frist: I can tell you things like,like..condoms..

George: You believe that tears and sweat might be able to transmit AIDS?
