Tesla CEO Elon Musk has spent at least $260 million trying to send Donald Trump back to the White House, according to new documents. The huge injection makes Musk one of the largest single political underwriters in the presidential race and underscores the enormous influence the world's richest man has over this year's election. According to documents filed with the Federal Election Commission (FEC) on Thursday, Musk donated $238 million to America PAC, the super PAC he created this year, which works to vote on Trump's behalf in key states.
