Stephen Colbert, Bill Maher, Colin Jost, Jimmy Kimmel on Trump's scientific mind in Best of Late Night
How much does Trump know about diseases? Turns out, not much.

According to Bill Maher, President Trump has just had "the talk" at the age of 71, and it was with Bill Gates.
During a meeting with the billionaire, the president asked if there was a difference between HIV and HPV, the tech giant said. That story prompted one late-night comic to wonder: If he's talking to Gates about sexually transmitted diseases, what's he talking to women like Stormy Daniels about? Computer science?
Gates also conveyed another odd story, one that involved a helicopter, a grand entrance and an attempt at impressing Gates' daughter. For that wild story, and late-night comic Stephen Colbert's wild reaction, take a look at today's Best of Late Night, above.
