If you used the Dept. of Labor for the National debt, you would be better off using the lefty rags. Bubba, it's the Dept. of the Treasury that handles that! Try here:

Also if you want to post assumtions about future deficits and debt, that would be the folks at the GAO:

Debt Held by the Public
As deficits accumulate in CBO’s baseline, debt held by the public rises from 77 percent of GDP ($15 trillion) at the end of 2017 to 91 percent of GDP ($26 trillion) by 2027 (see Table 5 on page 18). At that level, debt held by the public would be the largest since 1947 and more than twice the average over the past five decades in relation to GDP (see Figure 4). Beyond the 10-year period, if current laws remained in place, the pressures that are projected to contribute to rising deficits during the baseline period would accelerate and push debt up even more sharply. Three decades from now, for instance, debt held by the public is projected to be nearly twice as high, relative to GDP, as it is this year—a higher percentage than any previously recorded in the nation’s history.9
You should note that the CBO is not using the total National Debt but another measure. For the projected GDP growth as the CBO saw things in June, go to the chart on page 21. As to the accuracy of the CBO, I would trust more in the musings on the wall of the public bathroom stall.
