Early Life and Education
Poindexter was born and raised in Odon, Indiana, the son of Ellen (Sommers) and Marlan G. Poindexter. He pursued his undergraduate education at the United States Naval Academy and went on to study at the California Institute of Technology, where he trained as a nuclear physicist. That scientific background would later shape his interest in applying technology to military and intelligence problems.
Naval Career
As commanding officer of USS England (CG-22), Poindexter served in the Gulf of Tonkin, where his ship’s role included protecting aircraft carriers. During that command he pioneered the shipboard use of computers to manage the ship’s force portion of yard overhauls, an early instance of applying computing to naval logistics.
National Security Advisor
Poindexter served as National Security Advisor to President Reagan, a position from which he played a significant role in several major policy events. These included the Strategic Defense Initiative, Operation El Dorado Canyon carried out in response to Libyan terrorist attacks, and the Reykjavik Summit with Soviet leadership.
His tenure as National Security Advisor ended in the shadow of the Iran-Contra affair. In his congressional testimony, Poindexter admitted to destroying a presidential finding signed in December 1985 that had retroactively approved arms shipments to Iran, stating that its disclosure would have been politically embarrassing to President Reagan. That admission placed him at the center of the legal proceedings that followed.
Iran-Contra: Indictment, Conviction, and Reversal
On March 16, 1988, independent counsel Lawrence Walsh indicted Poindexter on seven felony charges. On April 7, 1990, he was convicted on all five counts that went to trial, which included conspiracy, obstruction of Congress, and making false statements.
U.S. District Judge Harold H. Greene sentenced Poindexter on June 11, 1990 to six months in prison on each of the five counts, with the sentences to be served concurrently. The conviction did not stand. On November 15, 1991, a three-judge panel of the U.S.
The Supreme Court declined to review the case on December 7, 1992. In 1993, the indictment was dismissed on the motion of independent counsel.
DARPA Information Awareness Office
From January 2002 to August 2003, Poindexter served as director of the DARPA Information Awareness Office (IAO). The office oversaw the Total Information Awareness (TIA) program, which was intended to use data-mining techniques to detect potential terrorist activity. In FY2003 alone, DARPA dedicated $137.5 million to research and development programs managed by the IAO.
A separate program under Poindexter’s purview, the Policy Analysis Market (PAM), proposed allowing users to buy and sell futures contracts tied to potential terrorist events. Within a day of its public announcement in July 2003, PAM was canceled following widespread criticism.
Congress defunded the Information Awareness Office in late 2003 after media reports criticized the government for attempting to establish broad surveillance over citizens. Poindexter resigned effective August 29, 2003. Among the awards he received is the Doublespeak Award.
