Aaron’s vice presidential candidacy comes under fire from the press, which questions his Mexican descent. He also faces pressure at the White House, and ends up arguing with Isabel. Kirkman and his staff negotiate an appropriate solution to an ongoing nationwide teacher’s strike, and Kirkman makes a decision about vetoing a bill. Wells and Mays’s investigation gets closer to who caused the bio attack, when they discover it targets people of color, suggesting that it was likely racially motivated. During the course of Kirkman’s day, Dontae films most of his daily schedule to promote his campaign. The campaign video is successful, but a conspiracy website suggests Alex's death was a presidential murder.
