I don’t need to. That’s not my job. That’s Vance’s to protect our nation. The article says Rubio (Sec of State) was against the Iran war too, so that’s one that shares his view on the Iran war. Its up to them to talk to other members of the Cabinet. Alternatively Vance can go to Congress and seek trump’s removal through other Constitutional means. If he chooses not to, and it didn’t look like he did, he’s equally responsible for all of trumps crimes.
