In another senior staff shake-up inside his often turbulent administration, US President Donald Trump has picked the two people he wants to be the next US attorney general and the next US ambassador to the United Nations.
Trump said he will nominate William Barr, who was attorney general under former President George HW Bush in the 1990s, to fill that top job again at the US Justice Department.
Barr would replace Acting Attorney General Matthew Whitaker, who has been in that position since Trump forced out Jeff Sessions as attorney general a month ago.
Trump will also put forward State Department spokeswoman Heather Nauert as ambassador to the United Nations. Nauert, a former Fox News Channel host, would replace Nikki Haley, who said in October she would resign at the end of this year.
Both are likely to face tough questions at their Senate confirmation hearings.
Democrats called Nauert unqualified and said they were concerned about Barr's independence. Republicans said they were pleased with both nominees.
Trump also said he would make a personnel announcement concerning the Pentagon on Saturday, telling reporters outside the White House, "It will have to do with the Joint Chiefs of Staff, the succession."
He is expected to name the Army's top general, Mark Milley, as the next chairman of the Joint Chiefs of Staff, the country's top military position, US officials said.
Separately, two sources told Reuters that John Kelly is expected to resign in coming days as White House chief of staff after months of speculation.
The proposed changes come as the Republican president faces another difficult stretch.
Democrats are promising aggressive oversight of Trump's administration and business activities when they take control of the US House of Representatives in January following their gains in last month's elections.
Special Counsel Robert Mueller is continuing to investigate Russian interference in the 2016 presidential election, any collusion between Moscow and Trump's campaign and possible obstruction of justice.
More details of the inquiry were set to emerge in court filings later on Friday.
Barr, who was attorney general under Bush from 1991 to 1993 and has worked in the private sector since then, would oversee Mueller's probe if the Senate confirms him in the job again.
He is likely to face pressure at his confirmation hearings to show he would protect Mueller from political interference. Critics of Trump have long been concerned that the president wants to end the Mueller probe.
If she is confirmed to the UN ambassador post, Nauert would bring little diplomatic experience to a highly visible international role.
"She's clearly not qualified for this job, but these days it seems that the most important qualification is that you show up on Donald Trump's TV screen," Democratic Senator Chris Murphy said on CNN.
Other nations with veto power on the UN Security Council are all represented by ambassadors with decades of foreign policy experience.
