It wasn't immediately clear from the alert system where the odor was first reported.
The ground stops comesamid ongoing issues at the nation's airportswhere travelers have been snarled by long lines amid a partial government shutdown.
On March 13, three Washington, D.C.-area airports eventually reopened after a shutdown prompted by an overheated circuit board that created a troublesome "strong odor," Transportation Secretary Sean Duffy announced. The source of the strong odor was traced to a circuit board that overheated, and it was replaced, Duffy said.
