OKLAHOMA CITY (AP) - Members of Oklahoma's congressional delegation say they're encouraged that President Obama is sending 30,000 more troops to Afghanistan.

Obama told the nation Tuesday night that his new policy was designed to bring the war ``to a successful conclusion.''

Rep. Mary Fallin, R-Okla., said she has concerns about whether 30,000 troops are enough to defeat the resurgent Taliban, and she disagreed with Obama's announcement of a withdrawal date.

Rep. Frank Lucas, R-Okla., said even though Obama committed to 10,000 troops less than what commanding general, Stanley McChrystal, requested, the decision shows the president listened to his field commanders.

Rep. John Sullivan, R-Okla., said the decision was ``overdue,'' but agreed it is ``the right course of action.''
