Bill Gates: Trump didn't know HIV and HPV were different

In a meeting with Bill Gates, President Donald Trump asked the Microsoft founder and philanthropist to explain if there is a difference between HIV and HPV more than once, according to video obtained by MSNBC.

Why it matters: Gates is one of the most prominent advocates for vaccines and curing diseases across the globe. It's noteworthy that Trump didn't know there was a difference between two very different sexually transmitted diseases.
