Trump national security adviser KT McFarland 'to step down'
President Donald Trump's deputy national security adviser, KT McFarland, has been asked to step down after just three months, US media say.
Ms McFarland, an ex-Fox News analyst, has reportedly been offered the role of ambassador to Singapore instead.
It comes days after Mr Trump removed his senior strategist Steve Bannon from the National Security Council (NSC).
The NSC advises the president on national security and foreign affairs.
Mr Bannon's appointment in January raised fears that the circle of top advisers was being politicised.
Analysts say the latest moves show Mr Trump's new national security adviser, Lt Gen HR McMaster, reshaping the NSC team appointed by his predecessor.
The previous national security adviser, Lt Gen Michael Flynn, was fired after just three weeks and three days in the job, after it emerged he had misled the vice-president over his conversations with Russia's ambassador to the US.
Ms McFarland was a favourite of Mr Flynn.
According to the New York Times, she did not endear herself to NSC staff by mentioning at one meeting that she was wearing Ivanka Trump shoes and telling them early on that they needed to "make America great again", echoing the president's campaign slogan.
