Sanders vows to help Clinton beat Trump, keeps rallying

Bernie Sanders promised on June 16 to work with presumptive Democratic presidential nominee Hillary Clinton to defeat Republican Donald Trump in the Nov. 8 election, but did not formally pull out of the race for the White House.

Sanders did not endorse Clinton during an online speech to his supporters, but made it clear he was shifting his focus to building a grassroots movement to fight for his liberal policy agenda and transform the Democratic Party.

"The major political task that we face in the next five months is to make certain that Donald Trump is defeated and defeated badly, and I personally intend to begin my role in that process in a very short period of time," the U.S. senator from Vermont said.

"I also look forward to working with Secretary Clinton to transform the Democratic Party so that it becomes a party of working people and young people, and not just wealthy campaign contributors," he said in a speech broadcast from his hometown of Burlington, Vermont.

"Defeating Trump cannot be our only goal. We must continue our grassroots efforts to create the America that we know we can become," he said. "And we must take that energy into the Democratic National Convention on July 25 in Philadelphia where we will have more than 1,900 delegates."
