Secret Service director Joseph P. Clancy — who was hired from the private sector in 2014 by President Obama amid a series of security breaches and employee misconduct in the agency — has told the White House that he plans to step down March 4, per Washington Post. His leaving now gives Trump a chance to choose his own head of security.

Potential replacements, per WaPo:

• George Mulligan, the Secret Service's COO, former Pentagon official and White House military office director.
• Former Clinton detail leader Larry Cockell.
• Former assistant director Mickey Nelson.
• Deputy Director William Callahan.
