WASHINGTON (AP) — President Bush's former spokesman, Scott McClellan, will testify before a House committee next week about whether Vice President Dick Cheney ordered him to make misleading public statements about the leaking of CIA agent Valerie Plame's identity.

McClellan will testify publicly and under oath before the House Judiciary Committee on June 20 about the White House's role in the leak and its response, his attorneys, Michael and Jane Tigar, said on Monday.

In his new book, "What Happened: Inside the Bush White House and Washington's Culture of Deception," McClellan said he was misled by others, possibly including Cheney, about the role of I. Lewis "Scooter" Libby in the leak. McClellan has said publicly that Bush and Cheney "directed me to go out there and exonerate Scooter Libby."
