WASHINGTON – President Barack Obama has endorsed Hillary Clinton to succeed him as president.
In an online video, Obama called on Democrats to unify behind his former secretary of state's bid and "build on the progress" of his eight terms in the White House.

"I want you to be the first to know that I'm with her," he said.
Obama also praised Democratic primary candidate Bernie Sanders for engaging young voters and highlighting the issues of income inequality and money in politics.
"Embracing that message is going to help us win in November," Obama said.
The move came after Obama met with Sanders.
Sanders said he would work with Clinton to stop Donald Trump.
In his endorsement, Obama said: "I don't think there's ever been someone so qualified to hold this office."
Republican presidential nominee Donald Trump was quick to respond after news broke about the endorsement.
"Obama just endorsed Crooked Hillary," Trump posted on Twitter. "He wants four more years of Obama -- but nobody else does!"
Clinton and Obama will campaign together in Green Bay, Wisconsin, on June 15.
