Obama says Trump 'unfit, challenges GOP to drop support

WASHINGTON (AP) — In a searing denouncement, President Barack Obama today slammed Donald Trump as "unfit" and "woefully unprepared" to serve in the White House.

He challenged Republican lawmakers to drop their support for their party's nominee, declaring "There has to come a point at which you say enough."

The president's blistering critique of his potential successor came on the heels of Trump's criticism of an American Muslim family whose son, a captain in the U.S. Army, was killed in Iraq. A growing number of GOP lawmakers have disavowed Trump's comments, but most of those who have endorsed him are sticking by that stance.

"If you are repeatedly having to say, in very strong terms, that what he has said is unacceptable, why are you still endorsing him?" Obama asked during a White House news conference. "What does this say about your party that this is your standard-bearer?"

The president said his opposition to Trump is about more than policy differences. He said that while he disagreed with his Republican opponents in the 2008 and 2012 elections, he never thought they were unfit to do the job.
