For the 2016 presidential transition, TFA was the nonprofit organization that facilitated the orderly transition of executive authority from President Barack Obama to President Donald J. Trump. Its activities were funded partially through congressional appropriations and partially through dollar-limited private contributions. See id. note 6(c), 7(a). TFA is a private and independent nonprofit organization; it is not controlled by and does not share employees with the White House, the GSA, or other federal agencies. In fact, most PTT personnel are volunteers, acting in their personal capacity, to advance TFAs nonprofit mission of peacefully and efficiently transferring executive power.
In other words, the transition team is not a government agency.
No reason for them to have .gov email accounts. Those aren’t given out like Halloween candy.
