President Bush has selected outgoing Florida Gov. Bob Martinez as the nation's new anti-drug director and planned to announce his nomination Friday, administration sources say.

Martinez, who left Tallahassee, Fla., for Washington Thursday, intends to join the president at the White House for a mid-afternoon announcement, the sources said.Martinez, a Republican, was defeated in his bid for re-election on Nov. 6 by Democrat Lawton Chiles. He would replace William Bennett as director of the Office of National Drug Control Policy.

The position is subject to Senate confirmation,

and he has already lined up the backing of Florida's two senators, Democrat Bob Graham and Republican Connie Mack. Chiles also has expressed support for him.

Bennett announced his resignation as anti-drug director on Nov. 8. His final day on the job is Friday. With the blessing of Bush, he is expected to become head of the Republican National Committee in January.

Administration sources first disclosed on Nov. 18 that Martinez was being considered as Bennett's successor, and the governor has since acknowledged discussing the post with White House aides.
