The four Democratic congresswomen attacked by US President Donald Trump in ‘racist’ tweets have collectively retaliated in a press conference, vowing they will ‘not be silenced’ and accusing the President of promoting a ‘white nationalist agenda’.

It comes after President Trump defended the tweets, saying he was not concerned if people thought they were racist and accusing the politicians of hating America.

Congresswoman Alexandria Ocasio-Cortez said the President challenged their loyalty to the country in order to avoid challenging and debating the policy.
