Democratic leaders in Congress changed course Friday from the bipartisanship that has characterized efforts to stimulate the economy, outlining a legislative agenda that challenges President Bush and other Republicans on a broad front.

Senate Majority Leader Harry Reid , D-Nev., called on Bush to use his State of the Union address Monday night to state explicitly that no arm of the federal government will engage in any form of torture, including the controversial simulated drowning technique known as waterboarding.

Reid also said Bush should announce the shutdown of the prison for terrorism suspects at Guantanamo Bay in Cuba and chart a draw- down of U.S. troops in Iraq.

House Speaker Nancy Pelosi , D-Calif., called for sweeping global warming legislation,, major health care initiatives, and large infrastructure investments.

“Perhaps he will take some of the steps I have discussed. If so, we extend our hand to him and all Republicans,” Reid said.

“But no matter what course the president takes this year, Democrats will keep fighting for change.”

At the White House, spokeswoman Dana Perino attempted to strike a more positive tone as she outlined what to expect from Bush’s State of the Union address.

Perino said the speech “ will identify potential areas of agreement with a Democratic Congress. And these areas of common ground include new policy proposals with realistic chance of enactment this year.”

But she made clear Bush also would continue to press lawmakers to fund the war in Iraq on his timetable and terms, not theirs.
