In a new Web video, President Barack Obama is asking Americans to help him pass his $3.6 trillion budget.

Obama asks views to "head outside this Saturday to knock on some doors, talk to some neighbors, and let them know how important this budget is to our future."

Obama said his budget will "lay a foundation for lasting growth and prosperity," by investing in health care, education and renewable energy. The spending plan projects a federal deficit of $1.75 trillion this year, by far the largest in history. But Obama says he can get it down to $533 billion by 2013.
