Carter's successor, Reagan, was to face difficulties of his own. His efforts to resolve another hostage situation led to the Iran-Contra affair. Many of the president's supporters believed that the aggressive management style of his White House Chief of Staff, Donald Regan, was making matters worse, but Reagan remained loyal to Regan and would not consider replacing him. A presidential adviser, Michael Deaver, as well as First Lady Nancy Reagan made a discreet approach to an experienced outsider they believed might be able to persuade Reagan. Others had told him what he wanted to hear: that the controversy would blow over and that Donald Regan was more useful than not being there. Strauss, who had closely observed the workings of two other presidential administrations, told Reagan the painful truth: Regan had become a liability and that the White House needed a Chief of Staff who could mend fences, especially with Congress.
