Deputy national security adviser K.T. McFarland is expected to leave her role following the resignation of national security adviser Michael Flynn, The New York Times reported Tuesday morning.
McFarland has worked under three Republican administrations and was selected last year to serve as deputy national security adviser under President Trump.
Flynn resigned late Monday after reports he misled senior White House officials about his conversations with Russia.
His future in the White House had come under speculation since reports surfaced last week that he spoke with Russia's U.S. ambassador about fresh sanctions levied against Moscow by the Obama administration before Trump was sworn in.
The reports contradicted Flynn's earlier comments that he never discussed the topic with Ambassador Sergey Kislyak during a series of phone calls the month before Trump took office.
A spokesman for Flynn walked back that denial last week, saying that while Flynn "had no recollection of discussing sanctions, he couldn’t be certain that the topic never came up."
Flynn blamed his resignation late Monday on the "fast pace of events" that led him to "inadvertently" give Vice President Pence and others "incomplete information" about his phone conversations with Russia's ambassador to the U.S.
He apologized to the president and vice president and said the two had accepted his apology.
