Former White House chief of staff Mick Mulvaney expects US President Donald Trump to choose a Fox News presented as Karoline Leavitt’s press secretary replacement. “It’s going to be someone who either already works for the president or somebody who works for his favourite media outlet Fox News,” Mr Mulvaney told News24. “I don’t think he wants to roll the dice on an unknown quantity. “Names that are already known, assistant secretaries, the assistant press secretaries and then celebrities or presenters on Fox News.”
