Donald Trump has said he would "encourage" Russia to attack any Nato member that fails to pay its bills as part of the Western military alliance. The White House called the comments "appalling and unhinged". Addressing crowds during the rally in South Carolina, Mr Trump said he had made his comments about Russia during a meeting of leaders of Nato countries. A White House spokesman said the former president was "encouraging invasions of our closest allies by murderous regimes", and labelled the comments "appalling and unhinged". Mr Trump celebrated that rejection during Saturday's rally, saying the proposals made by President Biden had been "disastrous".
