Ricardel remained at work on Tuesday as Bolton objected to her ouster and was reportedly at the office on Wednesday before her transition was announced.
Bolton brought Ricardel on board in May to serve as his No. 2 on the National Security Council. She earned a reputation as an enforcer and fierce bureaucratic infighter, clashing with White House chief of staff John Kelly and Defense Secretary James Mattis.
(18.10.2018) The three people said Mr. Kelly and Mr. Bolton were sparring over an issue that has frequently angered the president and has often prompted him to lash out at Kirstjen Nielsen, who succeeded Mr. Kelly as the secretary of homeland security after serving as his deputy chief of staff in the White House. Mr. Bolton was siding with the president, who has angrily blamed Ms. Nielsen for failing to stanch the flow of migrants across the border, while Mr. Kelly, who is fiercely protective of his protégé, defended her, the people said.
