Democrat Barack Obama writes in an opinion piece Monday in The New York Times that he would send at least two more combat brigades to Afghanistan.

Obama says there's a need for "more troops, more helicopters, better intelligence-gathering and more nonmilitary assistance to accomplish the mission there."

He says the additional troops for Afghanistan would come in part by redeploying combat brigades out of Iraq by the summer of 2010.

Obama writes that ending the Iraq war "is essential to meeting our broader strategic goals, starting in Afghanistan and Pakistan, where the Taliban is resurgent and al-Qaida has a safe haven."

Obama will deliver a speech in Washington tomorrow on Iraq and Afghanistan.

Republican John McCain's campaign says he will outline his plan for Afghanistan on Thursday.
