McCain joins Navajo families in condemning Donald Trump's 'Pocahontas' jibe

Republican senator John McCain has joined families of Navajo war veterans who were honoured at the White House in condemning Donald Trump over a "Pocahontas" jibe at a Democratic senator.

The families said they were dumbfounded that the president used the event to take a shot at Elizabeth Warren, demeaning their work with an unbreakable code that helped the US win the Second World War.
