President Tom Kirkman (Kiefer Sutherland) doubles down on the effort to identify the traitor in “Designated Survivor“‘s Season 1 finale, as seen in an exclusive clip above.

The scene from Wednesday’s episode shows the commander in chief informing Aaron Shore (Adan Canto) that the perpetrator might be a former member of President Richmond’s staff.

“What I’m about to tell you is strictly classified,” Kirkman says. “We know that there’s a traitor in the White House. We haven’t been able to identify him, but we know he was involved in the Capitol bombing and was instrumental in having me appointed as the designated survivor.”

Shore appears confused as to why Charles Langdon (Peter Outerbridge) is no longer presumed to be responsible for the explosion that killed Richmond and all the members of his Cabinet other than Kirkman.

“Langdon’s in custody,” the president explains to Shore. “The person we’re looking for is actively destroying evidence of the conspiracy. I know this is a lot to take in, but I would like you to go back over your records, see if anything stands out.”

Watch the drama unfold in the above clip.

“Designated Survivor”‘s Season 1 finale airs on Wednesday at 10 p.m. ET on ABC.
