Donald is a state senator running for re-election. He is Phil's father and Penny's uncle. Mark's first impression of him when they meet at one of his fundraising party is that Donald is an impeccability dressed, handsome man who looks like an older version of Phil.
Even tough Donald's fundraising parties play a key part in Phil's route Mark only meets him once, briefly on the first party he attends. On their encounter they exchange pleasantries and Donald looks concerned for Mark, who had accidentally got himself high on Ian's animal tranquilizers.
- Donald is a former marine who served in Vietnam.
