President Barack Obama says Donald Trump is waging a White House campaign based on "simplistic solutions and scapegoating."
In an interview on NBC, Obama says Trump is appealing to people's fears and uncertainty about the future. Asked how seriously the front-running Republican candidate should be taken, Obama says, "Talk to me if he wins."
But Obama concedes the country is more divided than he promised. When asked if he felt responsible for that, he said, "It's a regret."
But he said he "could not be prouder" of his accomplishments.
Vice President Joe Biden, who also appeared on the show, said "I think it's possible" that Trump could win the presidency.
If that happens, Biden added, "I hope that he gets a lot more serious about the issues, a lot more serious about gaining knowledge about how this nation functions in foreign policy and domestic policy."
