Mr Trump had been "very concerned" the retired army lieutenant general misled Vice President Mike Pence and others, spokesman Sean Spicer said.

Mr Spicer said General Flynn forgot "critical details" about his phone call on 29 December with Russia's ambassador to the US, Sergey Kislyak, creating "a critical mass and an unsustainable situation".
