Trump is the nominee of the Republican Party for President of the United States in 2016, having won the most state primaries, caucuses, and delegates to the 2016 Republican National Convention. Trump chose Indiana governor Mike Pence as his vice presidential running mate.
Tuesday is Donald Trump's 70th birthday. If he wins the election in November, that means he would be the oldest newly elected president in U.S. history, putting him ahead of Ronald Reagan, who was just shy of 70 on Inauguration Day 1981. If Hillary Clinton were elected, she wouldn't be far behind. She will turn 69 in October. Come Inauguration Day 2017, that would put her not far behind Reagan when he was inaugurated, making her the second-oldest president.
