WASHINGTON (AP) — President Bush's former chief political adviser denied meddling in the Justice Department's prosecution of Alabama's ex-governor and said Sunday the courts will have to resolve a congressional subpoena for his testimony.

"Congress, the House Judiciary Committee, wants to be able to call presidential aides on its whim up to testify," Karl Rove said. "It's going to be tied up in court and settled in court."

Last week, the committee ordered Rove to appear July 10. Lawmakers want to ask him about the White House's role in firing nine U.S. attorneys in 2006 and the prosecution of former Gov. Don Siegelman, D-Ala.

Also under congressional subpoena are Bush's chief of staff, Joshua Bolten, and his former counsel, Harriet Miers.
