Obama describes Trump as 'unfit' to serve as president
WASHINGTON - In a blunt and virtually unprecedented presidential rebuke, Barack Obama on Tuesday described Donald Trump as "unfit" to be president and called on Republicans to disown him.
Standing alongside the prime minister of Singapore, Obama cast aside any pretense of domestic unity and described Trump as "woefully unprepared" and "unfit to serve as president."
"He keeps proving it," Obama added.
"This isn't a situation where you have an episodic gaffe," Obama said as the 70-year-old mogul was embroiled in multiple controversies over his comments about Muslims, babies, firefighters and the military.
Obama turned up the heat on Republican leaders who have backed Trump, but continue to denounce some of his comments.
"This is daily and weekly where they are distancing themselves from statements he's making," Obama said.
"There has to be a point in which you say: 'This is not somebody I can support for president of the United States, even if he purports to be a member of my party.'"
Obama has endorsed Hillary Clinton in the 2016 White House race and has repeatedly pilloried Trump's populism.
But his comments in the East Room of the White House -- where Abraham Lincoln lay in state and Theodore Roosevelt today casts a painted gaze -- are a significant and highly personal escalation of presidential rhetoric.
"There have been Republican presidents with whom I've disagreed with, but I didn't have a doubt that they could function as president," Obama said.
Turning to his 2012 and 2008 election opponents, Obama said "Mitt Romney and John McCain were wrong on certain policy issues, but I never thought that they couldn't do the job."
Obama's comments came amid a roiling war of words between Trump and the father of a slain US soldier who rebuked the Republican nominee as having "sacrificed nothing."
Trump also has come under fire for remarks in a television interview in which he appeared not to be aware of Russia's 2014 annexation of Crimea after its takeover from Ukraine.
Obama said: "The notion that he would attack a Gold Star family that made extraordinary sacrifices on behalf of our country, the fact that he doesn't appear to have basic knowledge around critical issues in Europe, in the Middle East, in Asia means that he's woefully unprepared to do this job."
"There has to come a point in which you say 'enough'," he said, in a comment directed at Republicans.
"The alternative is the entire party and the Republican party effectively endorses and validates the positions being articulated by Mr Trump. As I said in my speech last week, I don't think that represents the views of a whole lot of Republicans out there."
Obama last week addressed the Democratic convention in Philadelphia and painted this election as a choice not between a Democrat and Republican, but a Democrat and a demagogue who threatens democracy.
