Deputy Attorney General Rod Rosenstein will remain at the Department of Justice for “a little while longer,” despite planning to leave before now, Fox News reports.

Rosenstein planned on leaving the department in mid-March, according to multiple reports in February. However, sources close to him told Fox News that he has yet to submit his two weeks notice, and that he is still the primary liaison between the DOJ and special counsel Robert Mueller’s office.

CNN reports that the decision to stay on came “after consulting with Attorney General William Barr,” who assumed office in February.

Rosenstein had been overseeing Mueller’s probe into Russian interference in the 2016 presidential election since former Attorney General Jeff Sessions recused himself, though Barr now has main oversight of the investigation.

The Senate Judiciary Committee is set to investigate alleged remarks that Rosenstein made to former FBI Deputy Director Andrew McCabe about possibly removing Trump from office under the 25th Amendment. Rosenstein has denied these statements.
