WASHINGTON (AP) – President Bush’s embattled anti-terrorism agenda got a boost Wednesday when a wiretap bill was revised and a Senate Republican leader said he was hopeful a deal was near on treatment of detainees.

Progress on the two critical issues before Congress recesses next week for the midterm elections was seen as crucial to Republicans as they defended their majorities in the House and Senate

In the Senate, neither the White House nor the rebellious senators had the votes necessary to move to move forward on how to handle the nation’s most dangerous terror suspects, however. The two sides remained at odds over how to adhere to the 1949 Geneva Conventions and – simultaneously – give the CIA wide leeway to conduct interrogations.

House Intelligence Chairman Peter Hoekstra, R-Mich., said he had not been briefed on late-night negotiations between Republican senators and the White House, but he expected significant differences between any bills passed by the House and Senate.

Yet “if the Senate and the White House have reached an agreement, that is probably what would end up becoming law and making its way to the president’s desk,” Mr. Hoekstra said at the conservative American Enterprise Institute think tank.

Despite the stalemate, Senate Republican Leader Bill Frist sought to reassure Republican troops that a deal still was possible.

” I am hopeful that very soon agreement can be reached with the president and with the majority of Republicans,” Mr. Frist said in a statement. “But we need to do it in a way that were not sharing classified information with those terrorists who clearly will pass it on to others around the world to be used against us.”

He spoke as House Republicans moved closer to the administration’s position on its domestic wiretapping program.

Rep. Heather Wilson’s bill initially would have given legal status to Mr. Bush’s domestic surveillance program only after an attack. Instead, her bill now would grant the administration’s plea to allow wiretapping against Americans without warrants when it is believed a terrorist attack is “imminent.”

But that concession carried a price for the president, according to a draft.

Under the measure, the administration would be required to share more details of the nature of the threat with the House and Senate leaders and the chairmen of both intelligence committees, who then would decide without administration input which lawmakers would receive the classified information.

“Excesses are best prevented when intelligence activities are operated within a framework that controls government power by using checks and balances among the three branches of government,” Ms. Wilson said in a statement.

Her substitute, being considered Wednesday by the House Intelligence Committee, represents a possible breakthrough in a bitter, election-season rift between the White House and Republican leaders on one side and Republican lawmakers concerned about Mr. Bush’s use of executive authority in his war on terror.

Also Wednesday, the House Judiciary Committee was considering the detainee issue under a bill passed 52-8 by the House Armed Services Committee last week. Rep. Adam Schiff, D-Calif., proposed bringing that bill more in line with the one proposed by the maverick Republicans, which would put more restrictions than the White House would like on the techniques that interrogators could use.

Under the Wilson bill, several parties must be notified in writing that “the president has determined that there exists an imminent threat of attack likely to cause death serious injury or substantial economic damage to the United States.”

The notification must:

_Be submitted within five days of the president’s authorization of the surveillance.

_Name the entity or entities responsible for the threat.

_State the reason for believing the attack is imminent, though the early draft obtained by the AP does not define the term.

_Describe the foreign intelligence expected to be obtained through the surveillance and the means of the surveillance.

The bill also would prevent the president or his designee from authorizing the surveillance of a person unless they have “a reasonable belief” that the subject is communicating with a group responsible for the imminent threat, and that the information obtained “may be foreign intelligence information.”

Ms. Wilson also added provisions that would spell out that the House and Senate intelligence committee chairmen would have sole discretion to share the information with all or any panel members and staff.
