The departures indicate unstable circumstances at the Department of Homeland Security, which oversees the Secret Service.
On the tail of the resignation of Homeland Security Secretary Kirstjen Nielsen and the withdrawal of the nomination of would-be ICE director Ronald Vitiello, Secret Service Director Randolph "Tex" Alles is leaving his position, as well, CNN first reported Monday.
But administration officials told Fox News on Sunday that Nielsen's background in cybersecurity made her a poor fit to handle border issues, while McAleenan best fits Trump's requirement of being the "toughest cop" on the frontier.

Mr Alles was appointed by Mr Trump in April 2017.
CNN reported that President Donald Trump instructed acting White House chief of staff Mick Mulvaney to fire Alles. This access does not afford an individual proximity to the President or other Secret Service protectees.
