Ex-Bush aide gives few answers at prosecutor probe

But Taylor said she never spoke to Bush about replacing the prosecutors or attended a meeting with the president about the matter.

Taylor also responded when asked about an e-mail she wrote this year in which she said "Bud (Cummins) is lazy -- which is why we got rid of him" as the U.S. attorney in Arkansas.

Taylor told the committee: "I would like to take this opportunity to apologize to Mr. Cummins. It was unkind and unnecessary."

Cummins was replaced by Tim Griffin, a former aide to Taylor and Rove.

With lawmakers challenging Bush's claim of executive privilege, the battle will likely go to the courts unless the White House and Congress reach a compromise.
