Washington ? Former Homeland Security Secretary Tom Ridge claims in a new book that he was pressured by other members of President George W. Bush’s Cabinet to raise the nation’s terror alert level just before the 2004 presidential election.

Ridge says he objected to raising the security level despite the urgings of former Defense Secretary Donald H. Rumsfeld and then-Attorney General John Ashcroft, according to a publicity release from Ridge’s publisher. In the end the alert level was not changed. Ridge said the episode convinced him to follow through with his plans to leave the administration; he resigned on Nov. 30, 2004.

Bush’s former homeland security adviser, Frances Townsend, said Thursday that politics never played a role in determining alert levels.
