FILE - In this March 19, 1987 file photo, President Ronald Reagan taps his forehead at the White House while responding to a reporter's question during a news conference at which he said he never deliberately lied to the public, despite admitting to a misstatement about Israeli involvement in the Iran-Contra affair. In a 1986 radio address admitting to missteps in the Iran-Contra scandal, the president famously said "mistakes were made" - a passive acknowledgement of wrongdoing that didn't directly implicate anyone.
