Billionaire philanthropist Bill Gates announced that he plans to donate his entire personal fortune, estimated at $200 billion, to the world's poor through his foundation. Speaking at his foundation's 25th anniversary, he noted that this move comes at a time when mutual cooperation between nations is not guaranteed - alluding to U.S. President Donald Trump's policy of refusing to continue humanitarian aid to world nations. He added that he is accelerating his plans to dispose of his wealth and close the Gates Foundation on December 31, 2045.
