Hope Hicks

The longtime Trump aide is the fourth person to fill the position, replacing Anthony Scaramucci, who was fired in July after just 10 days on the job.

Ms Hicks has served as President Donald Trump's strategic communications director and campaign press secretary.

The ex-Trump Organization employee is one of his most trusted aides.

As White House communications director she will be responsible for shaping the administration's message - although in a less visible way than press secretary Sarah Huckabee Sanders.

Hope Hicks replaces Anthony Scaramucci, who was fired after 10 days.

She doesn't have a background in politics, but has been connected to the Trump family for the last five years.

And she's quietly worked her way up to being one of the president's closest allies - and one of his highest paid, on $180,000 (£140,000) a year.

So how did someone with such a low profile get one of the most important jobs in the US government?

Hope Hicks started her career in public relations, where Ivanka Trump's fashion company was one of her clients.
