Sen. John Kerry (search) added to the uproar surrounding the testimony of former counterterror chief Richard Clarke (search) Saturday, saying the White House was engaging in "character assassination" to sidestep questions about its handling of national security.
"I don't think people want questions about character; I think they want questions about our security to be answered," Kerry said Saturday. "That's what this is about."
The presumptive Democratic nominee for president didn't stop there. He also called on National Security Adviser Condoleezza Rice (search) to testify publicly in front of the commission probing the Sept. 11, 2001, terror attacks.
"If Condoleezza Rice can find time to do '60 Minutes' on television before the American people, she ought to find 60 minutes to speak to the commission under oath," said Kerry. "We're talking about the security of our country."
Rice has been interviewed privately by commission members.
Later Saturday, Kerry appeared at the World's Fair Pavilion in St. Louis with former rival Rep. Dick Gephardt (search) and former Missouri Sen. Jean Carnahan to rally an enthusiastic partisan crowd. The Massachusetts senator repeated a pledge to institute responsible economic policies, announcing goals of cutting the deficit in half and creating 10 million new jobs.
Also Saturday, Kerry said he will undergo outpatient surgery on Wednesday in Boston to repair a tear in a tendon in his right shoulder. He sustained the injury on the campaign trail in January when his bus stopped short in Iowa.
Kerry's criticism of the White House comes after the Bush administration said that presidential staff advisers, such as Rice, cannot testify publicly before congressional bodies. The bipartisan, independent commission was created in 2002 by congressional legislation and Bush's signature.
Bush campaign spokeswoman Nicolle Devenish said Kerry and other Democrats are looking to exploit the work of the commission for political advantage.
"John Kerry seeks to distract Americans from his own failed ideas for protecting America from future attacks," she said in a statement. "John Kerry's backward-looking approach would return us to the failed policies of treating terror as a law-enforcement matter."
Kerry said the constitutional separation of powers could be protected despite the White House's objections.
"Certainly we can find a way to respect executive privilege (search), not to have it be an opening to the door, but nevertheless to accomplish America's needs to protect the security of our country," he said.
On Clarke, Kerry said: "Every time somebody comes up and says something that this White House doesn't like, they don't answer the questions about it or show you the truth about it. They go into character assassination mode."
Besides Clarke, Kerry cited the examples of former Treasury Secretary Paul O'Neill (search) and Medicare accountant Richard Foster.
O'Neill was fired as Treasury secretary in December 2002 after publicly questioning the need for additional tax cuts, a core campaign issue for Bush. Foster said he was prohibited by his superiors from sharing with Congress a much higher but more accurate cost estimate for the administration's Medicare program.
Kerry said until the commission completes its report, he will comment neither on Clarke's testimony nor on whether Bush did enough to protect Americans before the attacks. Kerry, who spent much of the past week on vacation in Idaho, said he had not heard or read any of the testimony before the commission.
He nevertheless criticized the administration for having "stonewalled" the investigation. Bush originally opposed the panel's creation, then opposed its request for a two-month extension of its work, but eventually relented on both counts.
