A brief U.S. government shutdown ended on Friday after Congress passed and President Donald Trump signed into law a temporary spending deal expected to push budget deficits past $1 trillion annually with new military and domestic outlays.

But Trump is expected to unveil on Monday a fiscal 2019 budget plan that will be based on rosy assumptions, including economic growth of 3.2 percent next year, a White House official said.

That level is well above the 2.5 percent growth achieved in 2017 and the 2.5 to 2.7 percent range of economists' forecasts for this year. The White House's plan also anticipates that the strong growth will go on for years, the official said, with 3 percent growth in 2021, only tapering to 2.8 percent in 2026.
