Moran says he'll use the town hall to address the federal contractors, small business owners and the more than 120,000 federal workers in his district.
The Democrat, who represents Alexandria, Arlington, and parts of Fairfax County, says a shutdown would be devastating to the entire Northern Virginia economy.
Moran was in office during the last government shutdown, in the mid-90s; He says the impact of a shutdown now could be worse because after the last shutdown, federal workers were reimbursed for the time off.
Moran says he's not sure that will happen if a shutdown occurs this year.
The town hall starts at 7:30 pm at Francis Hammond Middle School in Alexandria, Virginia.
