U.S. citizens once held by Iran advocate for Americans still behind bars

CBS News chief foreign affairs correspondent Margaret Brennan interviewed former U.S. hostages held by Iran, who are now advocating for Americans currently detained there. The conversation, which Brennan will preview on "The Takeout," comes as the issue of American prisoners in Iranian custody remains a longstanding diplomatic concern. Former hostages bring credibility and emotional weight to calls for the release of those still imprisoned, often pressuring the U.S. government to prioritize their cases in negotiations. The U.S. has historically used diplomatic channels and negotiations to secure the release of American detainees held by Iran, though progress has been inconsistent. Brennan's platform as moderator of "Face the Nation" gives significant visibility to the former hostages' advocacy efforts.
