President Obama has defended U.S. involvement in Libya, saying the international operation has protected thousands of people in the North African country. Obama said he did not violate the War Powers Resolution, a U.S. law that requires congressional approval within 60 days if U.S. forces are involved in hostilities. He said Libyan leader Moammar Gadhafi was threatening to massacre his people, and the United States, as part of an international coalition, took out Libyan air defense systems so humanitarian assistance could be provided. He said pressure is increasing on the Libyan leader, or as he put it, "the noose is tightening." He said he addressed the American people on Libya and briefed members of Congress and has done "exactly" what he said he would. He said the operation is limited in time and scope, and there have been no U.S. causalities and no risk of additional escalation. He said the narrow mission has been carried out in "exemplary fashion." But he said questioning whether he needs congressional approval for the mission has become a popular topic among some lawmakers. Meanwhile, Obama has called on Congress to take action that he says would strengthen the economy and help Americans who are struggling financially. President Obama said the nation's economic problems will not be solved immediately. He said Americans are still looking for work, or seeking better-paying jobs or ways to pay their bills. He said Congress can send him a bill that would make it easier for entrepreneurs to patent a new idea, and approve trade agreements that he said would support "tens of thousands" of American jobs. He said he wanted to continue tax cuts for the middle class, but eliminate some tax breaks for richer Americans in order to raise government revenue. Obama says any agreement to reduce the nation's deficit is going to require "tough decisions," including decisions on what he called "spending in the tax code" by eliminating some tax benefits for the wealthy. The president called reducing the deficit one of the most important and urgent things the U.S. government can do for the economy. He said he believes Republicans and Democrats can bridge their differences and reach a deal that will require the government to live within its means. He urged lawmakers to "seize this moment and seize it soon," saying that nobody wants to put the creditworthiness of the U.S. in jeopardy or see the U.S. default on its government debt, which officials have warned may happen if Congress does not raise the government's debt limit.
