Senator John McCain (R-AZ), Chairman of the Senate Armed Services Committee, speaking at a Senate briefing at the Kennedy Caucus Room, titled The New Administration and Iran Policy Options. The Arizona Republican said the nuclear deal was very deficient and that the Iranian regime must be held to account for its malign activities in the region, its crackdown on its own citizens and its defiance of Security Council resolutions related to a ban on ballistic missile testing. The briefing was organized by the Organization of Iranian American Communities in the U.S.  (Photo by Siavosh Hosseini/NurPhoto via Getty Images)
