President Bush extended a permit allowing the Palestine Liberation Organization to operate in Washington.
Bush cited national security interests on April 11 in extending for another six months his waiver on laws banning the group.
Presidents have routinely waived the laws, which date back to the 1980s, for six-month periods since the launch of the Oslo process in 1993.
The current PLO envoy, Afif Safieh is about to end his term and take up a new post in Moscow. His replacement has not been named.
