Controversial US billionaire Donald Trump has finally gone too far for some fellow candidates for the Republican presidential nomination.
He was not criticised when he called Mexican immigrants rapists, murderers and drug dealers, but was blasted when he disparaged Senator John McCain’s Vietnam War record.
After dismissing Mr McCain’s reputation as a war hero because he was captured in Vietnam and saying “I like people who weren’t captured,” Mr Trump declared: “I will say what I want to say.”
He insisted he would stay in the Republican primary field, despite rivals who say he has now shown he does not merit the presidency.
Mr Trump’s candidacy has proved to be a gift to Democrats, especially frontrunner Hillary Clinton, as they line up for their own bids for the nomination.
While he has taken the top spot in early national polls among Republicans, his brash, some say outlandish, world view would seem to make him unelectable in a nationwide election.
