President Barack Obama has blasted Donald Trump’s recent remarks about women, saying they would be intolerable even for someone applying for a job at a 7-Eleven convenience store.
At a rally supporting Hillary Clinton, Mr Obama also urged senior Republicans to formally withdraw their endorsement of Mr Trump as presidential candidate.
Many top Republicans have distanced themselves from Mr Trump over a video in which he boasts of groping women.
Mr Trump accused them of disloyalty.
He was particularly scathing about House Speaker Paul Ryan whom he described as a “weak and ineffective” leader.

Addressing a campaign rally in Greensboro, North Carolina, on Tuesday evening, Mr Obama referred to Mr Trump’s crude remarks about women, saying: “Now you find a situation in which the guy says stuff that nobody would find tolerable if they were applying for a job at 7-Eleven.”
He said: “You don’t have to be a husband or a father to say that’s not right. You just have to be a decent human being.”
Mr Obama questioned how senior Republican politicians could still want Mr Trump to be president.
“The fact is that now you’ve got people saying: ‘We strongly disagree, we really disapprove… but we’re still endorsing him.’ They still think he should be president, that doesn’t make sense to me,” he told the crowd.
Mr Obama was interrupted several times by anti-Clinton campaigners but seemed unfazed, saying: “This is democracy at work. This is great.”
The hecklers were escorted from the venue by security officials.
