By Roberta Rampton and Will Dunham WASHINGTON (Reuters) - President Barack Obama will deliver a speech to Americans and consult with lawmakers this week to sell his plan to go on the offensive against Islamic State militants, but is trying to head off public concern about another big military escapade. Obama said that in his remarks on Wednesday he would "describe what our game plan's going to be." He will meet congressional leaders on Tuesday to seek their support for his strategy to halt the militant Islamist group. Obama indicated he did not believe he needed additional authorization from Congress to carry out the plan, although he intends to consult with lawmakers and might seek approval for additional funds. "I'm confident that I have the authorization that I need to protect the American people," Obama said.
