"Pelosi to Block Vote on Colombia Trade"
"Defying the White House, Nancy Pelosi said Wednesday the House will change its rules to avoid a required vote this year on a hotly disputed free-trade agreement with Colombia.
Pelosi said she will bring a procedural change to the House floor on Thursday that would remove the timetable under which Congress would have had to take up trade bills within 90 legislative days after they are received from the White House....
Pelosi insisted that the House's right to determine its own procedures overrides any requirements that Congress take up a measure within a prescribed time period."
