WASHINGTON (CNN) -- House Speaker Nancy Pelosi vowed Friday the chamber will pass a new Iraq spending bill by the end of next week, despite expressing disappointment earlier in the day over a negotiations meeting with Bush administration officials.

Asked by CNN's John Roberts if she was willing to capitulate a withdrawal timetable and strict benchmarks in a new bill, the California Democrat maintained any measure will hold President Bush "accountable."

"I know what the president is saying," Pelosi said. "He is saying, 'I don't want any accountability. Just give me a blank check for a war without end. Don't have the Iraqi government held accountable for not having political solutions while our young people die.' That's what the president is saying. I hear it very clearly."

"We'll have a proposal that supports our troops and we'll have it in a timely fashion," she added. "But we will also have it in a way that holds the president much more accountable than he wants to be."

After meeting with White House Chief of Staff Joshua Bolten, Pelosi said of the president, "He will not accept any accountability or responsibility for what is happening there. So that has made a meeting that we entered into in a hopeful way, that we could find our common ground, one where the line is drawn between accountability or none."

Roberts' full interview with Pelosi airs Monday on American Morning, 6-9 a.m. ET.
