Washington (CNN) - President Barack Obama's decision to send another 30,000 troops to Afghanistan met with a mixed reaction among Capitol Hill Democrats Tuesday. Leading Republicans backed the additional deployments, but questioned the creation of a three-year withdrawal timetable.
The sharp disagreement among members of Obama's own party indicates potential political trouble for the president as he tries to rally the country around his decision to expand American involvement in the eight-year conflict.
Obama is slated to announce the new troop deployments - along with the three-year withdrawal plan - in a speech at the U.S. Military Academy at West Point, New York, on Tuesday night.

Sen. Russ Feingold, D-Wisconsin:
"I am not in favor of what I have heard so far. ... Fundamentally I think increasing troops is not the answer, and I will be actively opposing it. I am confused why we would spend three years taking enormous loss and enormous cost in Afghanistan where we have other priorities that are greater."
Sen. Bernie Sanders, I-Vermont (caucuses with Democrats):
"It's a reaction of disappointment. This country is in the midst of a severe recession. We need to invest in our young people. We need to invest in infrastructure. We need to invest in sustainable energy. ... This is an international issue. This is not just an American issue. Where is Europe? Where is Russia? Where is China? Are they just sitting around and saying we don't have to do anything because Uncle Sam is going to pay the bills?"
Sen. Claire McCaskill, D-Missouri:
"I'm hopeful this president has taken the time and made the effort to think through whatever mission we will have over there. How we will accomplish it within a reasonable timeframe with some kind of certainty to the American people. The surge came about in Iraq because this kind of deliberative thought never occurred in the Bush administration as it related to (the) conflict in Iraq."
Sen. Mary Landrieu, D-Louisiana:
"I generally support (Obama's plan) but I have two concerns. One, that we find a way to pay for this, not just charge it to our children and grandchildren. Secondly, I want to know more about the increase of troops and resources because I'm not convinced we can ultimately defeat the Taliban with military might alone. ... I want to support increased muscle but that muscle has to be attached to increased hope and opportunity and economic support."
Sen. Bob Casey, D-Pennsylvania:
"We have to be very thoughtful about this. We have to get it right. The stakes are higher than they were in Iraq. It's going to take a lot of work in both parties. ... Just as the president engaged in a multi-week review, I think the Congress needs to do the same as well. ... We have to get it right, and if that means there's a division (then) there's a division."
Rep. Jane Harman, D-California:
"Expanding our military footprint in Afghanistan is a mistake. A larger occupation gives the Taliban an enhanced recruiting tool, continues the dependency of Afghan fighters on our superior training and logistics, and commits scarce U.S. resources ... at a time when other counterterrorism challenges - including inside the United States - appear more urgent."
Rep. Steny Hoyer, D-Maryland:
"Across the spectrum (the Democratic) caucus is concerned about the failure to succeed in Afghanistan. ... There is significant concern about whether or not we can be successful. ... It is a free-world responsibility, and the free world ought to participate in a proportional way."
Sen. Kit Bond, R-Missouri:
Obama is "finally doing the right thing. ... (But) announcing a withdrawal date is a little bit like telling people you're going to play the first three quarters of a football game and then you're going to take the first team off the field. I think those decisions need to be made by the commanders on the ground."
Sen. John McCain, R-Arizona:
"Certainly I support the (additional 30,000 troops) but I am very concerned about whether there is a date certain for withdrawal. Success is what causes us to withdraw. You don't want to tell the enemy you're coming and you're leaving."
Sen. Saxby Chambliss, R-Georgia:
"I am on board with giving Gen. McChrystal exactly what he asked for in terms of more troops." But "I have no idea" what (Obama's thinking is) in establishing a three-year withdrawal timetable. "It's pretty obvious where we're going to be three years from now. We'll be in the middle of another election."
