The federal deficit ballooned at start of new fiscal year, up 77 percent from a year before

The federal budget deficit ballooned rapidly in the first four months of the fiscal year amid falling tax revenue and higher spending, the Treasury Department said Tuesday, posing a new challenge for the White House and Congress as they prepare for a number of budget battles.

The deficit grew 77 percent in the first four months of fiscal 2019 compared with the same period one year before, Treasury said.
