WASHINGTON (CNN) -- Sen. George Voinovich, a Republican from Ohio and a member of the Senate Foreign Relations Committee, said Wednesday he is "skeptical" an increase in Iraq troop levels is the right strategy to pursue.

"At this point I am skeptical that a surge in troops alone will bring an end to sectarian violence and the insurgency that is fomenting instability in Iraq," Voinovich said in a statement. "The generals who have served there do not believe additional troops alone will help. And my faith in Prime Minister al-Maliki's political will to make the hard choices necessary to bring about a political solution is fragile at best."

Voinovich was one of a handful of senators who met with President Bush Wednesday to discuss his upcoming speech.

GOP Sens. Norm Coleman of Minnesota and Sam Brownback of Kansas also said Wednesday they are against a troop increase.
