Fresh divisions are emerging within the US Republican Party over its presidential candidate Donald Trump.
Republican donor Meg Whitman has endorsed his rival Hillary Clinton, saying Mr Trump’s “demagoguery” had undermined the national fabric.
Senior party activist Jan Halper-Hayes told the BBC she thought Mr Trump was “psychologically unbalanced”.
In the latest controversy, Mr Trump has refused to support two senior figures in his own party.
In an interview for the Washington Post, he said he was “just not quite there yet” when asked if he would endorse House Speaker Paul Ryan and Senator John McCain, who are up for re-election in November. Both men have publicly criticised him.
Mr Trump’s war of words with the bereaved parents of a US Muslim soldier killed in Iraq has triggered criticism of the Republican nominee from across the political spectrum and from veterans’ groups.
