President-elect Donald Trump continues to flesh out his cabinet with appointments this holiday weekend of Kathleen Troia "K.T." McFarland as deputy national security adviser, and attorney Donald McGahn to as White House counsel.

NBC News reports that McFarland, until recently a contributor at Fox News, has been a national security and defense expert in both the Ford and Reagan administrations. She is Oxford educated and even sought to run against Hillary Clinton in New York's 2006 Senate race, where she was ultimately defeated in the Republican primary.

McGahn, who has been serving as counsel to Trump's transition team, has been asked to assume his new position to possibly navigate some of the potential hazards that may spring from Trump's conflicts of interest between the political and business worlds.

More from NBC:

Politico has reported that McGahn, who has longstanding familial ties to the Trump organization and an "inside the Beltway" background as a former chairman of the FEC, may be tasked with putting distance between the president-elect and his myriad of business interests, which critics have argued could present unprecedented number of conflicts of interest and potential Constitutional crisis for the incoming administration.

Neither position requires Senate approval for confirmation.
