Former Tennessee Gov. Lamar Alexander, the nation's new education secretary, says he hopes to be a "spark plug" for change.

"I am eager to go to work, said Alexander in a statement Thursday after the Senate confirmed him as President Bush's selection to succeed Lauro Cavazos, who resigned under pressure by the White House.The Senate confirmed Alexander, 50, after an investigation found no evidence of violations involving financial dealings that netted him millions of dollars.

With the education post filled, Bush now has a complete Cabinet after a midterm shuffle that brought in new secretaries of agriculture, labor and education.
