WASHINGTON — Billionaire Bill Gates, a philanthropist and co-founder of Microsoft, said he met with President Donald Trump at the White House on Wednesday to advocate for continuing foreign aid disbursements from the U.S. Agency for International Development. "I went by the White House because there's a lot in this transition, what we keep, in terms of foreign aid, what we keep — it's all kind of up in the air," he told NBC’s "TODAY" show anchor Savannah Guthrie in an interview. "And I'm doing my best to make sure we keep the things that I think are very value-based."
