Ronald Reagan [SEP] Assassination attempt
On March 30, 1981, Reagan, his press secretary James Brady, Washington police officer Thomas Delahanty, and Secret Service agent Tim McCarthy were struck by gunfire from would-be assassin John Hinckley Jr. outside the Washington Hilton hotel. Although "close to death" upon arrival at George Washington University Hospital, Reagan was stabilized in the emergency room, then underwent emergency exploratory surgery. He recovered and was released from the hospital on April 11, becoming the first serving U.S. president to survive being shot in an assassination attempt. The attempt had a significant influence on Reagan's popularity; polls indicated his approval rating to be around 73 percent.
