James Mattis was President Donald Trump's first defence secretary - but resigned in 2018
Ex-US Defence Secretary James Mattis has denounced President Donald Trump, saying he deliberately stokes division.
He said he was "angry and appalled" by Mr Trump's handling of ongoing protests over the death of African American George Floyd at the hands of police.
Mr Mattis berated Mr Trump's "abuse of authority" - and backed protesters seeking to uphold American values, as did ex-President Barack Obama.
