There's a new director of communications in the White House.

Sean Spicer is out and former Wall Streeter Anthony Scaramucci is in.

US correspondent Richard Arnold told Mike Hosking the White House will be hoping Mr Scaramucci gives Team Trump a boost.

"In the past the new spokesperson has differed with his new boss on issues like guns and climate change but says he is a team player and so he has deleted his old tweets and is now a voice for hire."
