Adam verifies that no conference call has been booked with Hammond.
Sherry enters Keeler's campaign headquarters and offers him a way to win the election against her ex-husband. She explains that she was an accessory to the murder of Alan Milliken, and that Palmer lied to the police in order to hide it. Sherry has the prescription bottle that Milliken was reaching for when he suffered a heart attack. She knows that Palmer will drop out of the race if Keeler blackmails him for the evidence. In return, Sherry wants a job on Keeler's White House staff.
Wayne tells Palmer that one his sources claims Sherry met privately with Senator Keeler. Although Wayne wants to assign someone to find out the reason, Palmer insists that they ignore it to focus on the virus threat.
