Tom Steyer
On July 9, 2019, Steyer announced his candidacy for President of the United States in the 2020 election. He stated that he would be running in the Democratic primaries in an online campaign video. He dropped out of the race after losing the South Carolina primary on February 29, 2020. Steyer spent $250 million of his own money on his campaign. This was more than any other candidate in history, except Mike Bloomberg's campaign.
