Obama: Trump ‘dangerous’ for suggesting he won’t concede

MIAMI GARDENS, Fla. — Calling it “dangerous,” President Barack Obama said Thursday that Donald Trump’s attempt to “sow the seeds of doubt” about the integrity of elections in America undermines U.S. democracy and does the work of the nation’s adversaries.

“That is not a joking matter,” Obama said at a campaign rally for Trump’s rival, Democrat Hillary Clinton.
