Obama: Trump is unfit to be president

In a searing denouncement, President Barack Obama castigated Donald Trump as “unfit” and “woefully unprepared” to serve in the White House. He challenged Republicans to withdraw their support for their party’s nominee, declaring, “There has to come a point at which you say ‘enough.’ “

While Obama has long been critical of Trump, his blistering condemnation Tuesday was a notable escalation of his involvement in the presidential race. Obama questioned whether Trump would “observe basic decency” as president, argued he lacks elementary knowledge about domestic and international affairs and condemned his disparagement of an American Muslim couple whose son was killed while serving in the U.S. Army in Iraq.

A chorus of Republicans has disavowed Trump’s criticism of Khizr and Ghazala Khan, and the Republican nominee’s calls to temporarily ban Muslims from coming to the U.S. But Obama argued that isn’t enough.

“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?” No prominent Republican lawmaker responded to Obama’s challenge.

Instead, it was Trump stunningly withholding his support from top GOP lawmakers, including House Speaker Paul Ryan. In an affront to his party’s top elected official, Trump told The Washington Post he wasn’t “quite there yet” on an endorsement for Ryan in his primary next week.

Trump’s refusal to back Ryan exposed anew the deep divisions within the GOP and underscored that the businessman rarely plays by the traditional political playbook. Ryan has been among those urging Republicans to rally around Trump, despite concerns about his candidacy.

Ryan’s campaign said, “Neither Speaker Ryan nor anyone on his team has ever asked for Donald Trump’s endorsement. And we are confident in a victory next week regardless.”

Trump also said he was not supporting Sen. John McCain in his primary in Arizona, and he dismissed Sen. Kelly Ayotte as a weak and disloyal leader in New Hampshire.

Democratic nominee Hillary Clinton sees those GOP concerns about Trump as an opportunity to reach out to party moderates – particularly women – who may be so upset by the nominee that they’re willing to look past policy differences and questions about Clinton’s character.

One of those Republicans came around to Clinton’s side Tuesday. Hewlett-Packard executive Meg Whitman, a prominent GOP fundraiser and donor, endorsed Clinton and said, “Donald Trump’s demagoguery has undermined the fabric of our national character.”
