Attacks on Republican presidential hopeful Donald Trump abounded on the third night of the Democratic National Convention, with former New York mayor Michael Bloomberg dismissing him as a "dangerous demagogue".
Endorsing Democratic presidential candidate Hillary Clinton, Mr Bloomberg said the richest thing about Mr Trump is his "hypocrisy".
"There are times when I disagree with Hillary Clinton," he said. "But let me tell you - whatever our disagreements may be, I've come here to say we must put them aside for the good of our country.
"And we must unite around the candidate who can defeat a dangerous demagogue."
Khizr Khan got huge cheers as he challenged Donald Trump to "read the US constitution" and accused him of "sacrificing nothing" for America.
