In spirit I don’t disagree but how can the Department of the Interior do this? What is the specific action?
Also why would The Department of the Interior be responsible for travel conditions rather than something like The Department of Transportation?
E: I still don’t follow, what action can be taken by any agency to make travel fearless in time of pandemic?
Department of State carries out U.S. foreign policy. What can they do to change the reality of a pandemic?
Government information advertisement (something like you still have right to life and freedom of travel, pandemic doesn't change that, followed by advice on safe travel without risking someone else's health), conscription, personal protective equipment distribution.
What?
We need to ramp up testing and find a vaccine. We do not need to encourage travel. Quite the opposite.
EDIT: I looked up; the Department of Health or the Department of State would be more fit for purpose. Not the Department of Homeland Security, because TSA is actually a Travel Security Agency despite it is named Travel Safety Agency.
