Obama: Donald Trump Is 'Unfit' to Be President

President Obama said Republican presidential nominee Donald Trump is "unfit to serve as president."

In a press conference with Singapore's prime minister, Obama added that Trump has shown he is "woefully unprepared to do this job" after his comments on military families as well as his handle on foreign affairs.

"He doesn't appear to have basic knowledge around critical issues in Europe" and the Middle East, the president said.
