AARON SHORE (Adan Canto)
Every inch Wall Street, former White House Chief of Staff Aaron Shore is slick, suited and very much a young career politician. Rising to the job following the Capitol attack, chosen by Kirkman for his greater experience over Emily Rhodes, Aaron quickly overcomes his uncertainties about the new President and proves himself loyal, beginning a budding romantic relationship with Emily.
After McLeish is exposed as a traitor, and Aaron is suspected by Emily of being connected, Kirkman is forced to sideline him until the allegations die down. Aaron briefly goes to work for Republican Congresswoman Kimble Hookstraten but it looks like he may be on course back to the White House permanently once more.
