President George W. Bush extended for six months permission for the Palestine Liberation Organization to maintain an office in Washington.
Bush acted by waiving provisions of the Anti-Terrorism Act of 1987 that prohibited the PLO from having an official presence in Washington.
"I hereby determine and certify that it is important to the national security interests of the United States to waive the provisions," Bush wrote to Secretary of State Condoleezza Rice.
After the ban became law, PLO founder and longtime chief Yasser Arafat renounced violence and recognized Israel the next year, and official US-PLO contact began a month later, in December 1989.
President Bill Clinton was the first to waive the restriction, in 1993, and it has been waived continually since then.
