Hillary Clinton is warning Democrats not to be complacent in the 2020 campaign for the White House because President Trump will do whatever he has to in order to stay competitive in the race.

Clinton, the 2016 Democratic presidential nominee, former secretary of state, ex-New York senator, and first lady for eight years, lost the 2016 election to Trump by an unexpected 77 electoral votes but often reminds people she won the popular vote by 2.9 million ballots.
