Because of both President and Mrs. Reagan, in particular Mrs. Reagan, we started a national conversation when before nobody would talk about it, nobody wanted to do anything about it. That too is something that I really appreciate, her very effective, low-key advocacy but it penetrated the public conscience and people began to say, hey, we need to do something about this too.

Immediately after the segment aired social media erupted in criticism. Chad Griffin, President of the Human Rights Campaign (which endorsed Clinton for President in January) sent out this tweet calling Nancy Reagan “no hero” on HIV/AIDS:

While I respect her advocacy on issues like stem cell & Parkinson's research, Nancy Reagan was, sadly, no hero in the fight against HIV/AIDS

About two hours after her appearance, Clinton walked back her statement:
