"The question of impeachment is something that would divide the country," Pelosi said this morning during a wide-ranging discussion in the ornate Speaker's office. Her top priorities are ending the war in Iraq, expanding health care, creating jobs and preserving the environment. "I know what our success can be on those issues. I don't know what our success can be on impeaching the president."He also notes she said she "would probably advocate" impeachment of Bush and other administration officials if she were not a member of the House, but feels that it the process would slow the progressive agenda she's trying to push through.
