WASHINGTON (AP) — The Latest on the White House chief of staff (all times local):

4:20 p.m.

President Donald Trump's top pick to replace John Kelly as chief of staff, Nick Ayers, is no longer expected to fill that role.

That's according to a White House official who is not authorized to discuss the personnel issue by name and spoke on condition of anonymity.

Ayers is Vice President Mike Pence's chief of staff.

The official says that Trump and Ayers could not agree on Ayers' length of service. The father of young children, Ayers had agreed to serve in an interim capacity though the spring, but Trump wanted a two-year commitment.

The official says that Ayers will instead assist the president from outside the administration.

Trump announced Saturday that Kelly would be departing the White House around the end of the year.
