Trump was inaugurated as the 45th president of the United States on January 20, 2017. He imposed import tariffs which triggered a trade war with China, recognized Jerusalem as the capital of Israel, and withdrew U.S. troops from northern Syria. Trump met three times with North Korea's leader Kim Jong-un, but talks on denuclearization broke down in 2019. Before the 2016 election, The New York Times speculated that Trump 'accelerated his ferocious efforts to gain stature within the political world' after Obama lampooned him at the White House Correspondents' Association Dinner in April 2011.In 2011, the superintendent of the New York Military Academy at the time, Jeffrey Coverdale, ordered the headmaster of the school, Evan Jones, to give him Trump's academic records so he could keep them secret, according to Jones.
