Ten lawmakers representing the National Capital Region sent a letter to the secretaries of the Defense and Interior on Tuesday expressing “serious concerns” about the possibility of a gathering sparking an outbreak, noting that stay-at-home orders in Virginia, Washington, D.C., and Maryland are still in effect.

“Given the current COVID-19 crisis, we believe such an event would needlessly risk the health and safety of thousands of Americans,” the lawmakers wrote. The letter was spearheaded by Rep. Don Beyer (D-Va.) and signed by Sens. Ben Cardin (D-Md.) and Chris Van Hollen (D-Md.) and House Majority Leader Steny Hoyer (D-Md.), among others.

“Further, this event would come at the cost of millions of taxpayer dollars while we are facing an unprecedented economic downturn due to the pandemic,” they added.
