Washington, D.C. ? Another Republican senator said Friday he would back the symbolic push to oppose President Bush’s plans to increase troop levels in Iraq.

Kansas Sen. Sam Brownback, a recently announced presidential candidate who once supported Bush’s foreign policy, became the seventh Republican senator to line up behind a nonbinding rebuke of the troop proposal.

Brownback said he favors a measure sponsored by Sen. John Warner, R-Va., that expresses disagreement with the president’s plan and advocates a less central role for the U.S. military in stopping sectarian violence in Iraq.
