Vice President George H.W. Bush was en route to Texas at the time of the assassination attempt. Bush immediately headed back to Washington, but the lack of a secure phone line between his plane and the White House contributed a brief sense of confusion within the administration. The result was Secretary of State Alexander Haig's infamous declaration that he was "in control ... pending the return of the vice president." Penelope Bresse/Getty Images
After the attack, Reagan joked with his wife saying he "forgot to duck" and asked the attending doctors if they were Republicans. The president and first lady seen here outside the hospital. Ronald Reagan Library/Getty Images
