(FILES) In this file photo taken on April 21, 2018 Co-Chair of the Bill & Melinda Gates Foundation, Bill Gates, speaks during the discussion 'Building Human Capital: A project for the world' in the IMF/World Bank spring meeting in Washington, DC. Bill Gates is not a huge fan of Donald Trump, and at a recent event hosted by his foundation, he made that clear as he revealed details about his interactions with the US president. The billionaire Microsoft founder drew laughter from the crowd when he said that at two meetings, Trump needed help distinguishing the HIV virus, which can lead to AIDS, from HPV, a sexually transmitted disease that can cause cervical cancer or genital warts."Both times, he wanted to know if there was a difference between HIV and HPV so I was able to explain that those are rarely confused with each other," Gates said, in video footage of the meeting broadcast late May 17, 2018 by MSNBC. / AFP PHOTO / ANDREW CABALLERO-REYNOLDS
