Senators say Katrina probe stymied

WASHINGTON — The White House is crippling a Senate inquiry into the government's sluggish response to Hurricane Katrina by barring administration officials from answering questions and failing to hand over documents, senators leading the investigation said Tuesday.

In some cases, staff at the White House and other federal agencies have refused to be interviewed by congressional investigators, said the top Republican and Democrat on the Senate Homeland Security and Governmental Affairs Committee. Agency officials also won't answer questions about times and dates of meetings and calls with the White House, the senators said.

"No one believes that the government responded adequately," said Sen. Joe Lieberman, D-Conn. "And we can't put that story together if people feel they're under a gag order from the White House."

White House spokesman Trent Duffy said the administration is committed to working with separate Senate and House investigations of the Katrina response but wants to protect the confidentiality of presidential advisers.

"There is a deliberate process, and the White House has always said it wants to cooperate with the committee but preserve any president's ability to get advice from advisers on a confidential basis," Duffy said. "And that's a critical need for any U.S. president and that is continuing to influence how we cooperate with the committees."

Sen. Susan Collins, R-Maine, the committee's chairwoman, said she respects the White House's reluctance to reveal advice to President Bush from his top aides, which is generally covered by executive privilege. Still, she criticized the dearth of information from agency officials.

"We are entitled to know if someone from the Department of Homeland Security calls someone at the White House during this whole crisis, period," Collins said. "So I think the White House has gone too far in restricting basic information about who called whom on what day."

Moreover, she added, "It is completely inappropriate" for the White House to bar agency officials from talking to the Senate committee.

Collins and Lieberman sidestepped questions about whether they plan to subpoena the White House to get the information they seek.
