Leading members of President Bush's Republican Party on Sunday criticized mistakes and "incompetence" in his Iraq policy and called for an urgent ground offensive to retake insurgent sanctuaries.

In appearances on news talk shows, Republican senators also urged Bush to be more open with the American public after the disclosure of a classified CIA report that gave a gloomy outlook for Iraq and raised the possibility of civil war.

"The fact is, we're in deep trouble in Iraq ... and I think we're going to have to look at some recalibration of policy," Republican Sen. Chuck Hagel of Nebraska said on CBS's "Face the Nation."

"We made serious mistakes," said Sen. John McCain, an Arizona Republican who has campaigned at Bush's side this year after patching up a bitter rivalry.

Sen. Richard Lugar, an Indiana Republican and chairman of the Senate Foreign Relations Committee, also criticized the administration's handling of Iraq's reconstruction.

Only $1 billion of $18.4 billion allocated by Congress for the task has been spent, Lugar said. "This is the incompetence in the administration," he said on ABC's "This Week."
