President Barack Obama is urging Congress to pass a smaller set of spending cuts and tax changes while they hash out a broader budget deal.Lawmakers face a March 1 deadline when automatic, across-the-board spending cuts, already postponed once, take effect.

In his weekly radio and Internet address, Obama says he still wants a comprehensive package that deals with the debt. But he says that takes time. He's asking lawmakers to move forward with a short-term deal as they continue working on a longer-term solution.

He says if the cuts aren't averted, the military, middle-class families and the economy could suffer.

In the Republican address, Sen. Lisa Murkowski of Alaska says the U.S. must ramp up domestic energy production by streamlining regulations, investing in research and approving the Keystone XL pipeline and cited a report she issued this week.

"To take full advantage of our energy opportunities—and to face up to our energy challenges—this week I released a report entitled, Energy 20/20: A Vision for America’s Energy Future," she said in the GOP address. "It’s based on a simple insight: energy is good. Energy provides the basis of modern society and allows us to lead comfortable and productive lives. It allows us to produce food and manufacture and communicate."

"America’s energy infrastructure has aged, the price of oil is high, and the need for reliable energy has never been more urgent," Murkowski says. "Projects are too often hamstrung by burdensome regulations, delayed permits, and overzealous litigation. Our energy situation has improved in some respects, but we can still demand better.
