Five Republican Senators, including the influential John Warner, are now publicly opposed to President Bush's increase of troops in Iraq. House Republicans want the White House to submit monthly progress reports on what they call "strategic benchmarks" of progress. General David Petraeus, who takes over from General George Casey, will carry out the increase of 21,500 troops in Iraq. Petraeus appeared for confirmation before the Senate Armed Services Committee, now run by the Democratic majority. He said the focus of the additional troops will be less on killing insurgents than on security in civilian neighborhoods. We get reaction.
