US President Donald Trump's close associate, Hope Hicks, is named director of communication at the White House, post considered the most important in Washington.

Hope Hicks is one of the ones who worked with President Trump the longest since the campaign. She was appointed to the post of communications director temporarily when she replaced Anthony Saramuccin, who was dismissed in July after less than two weeks in office.

Hicks was a press secretary during the campaign and then a consultant with the White House. She had previously worked for the Trump Organisation, including his daughter's company, Ivanka Trump.

The 28-year-old has hired a Justice Department lawyer to represent him in the investigation into possible ties with Russia on the part of President Trump and Russia's campaign officials.
