-BftB’s Dr. Helfand

The White House Military Office Coast Guard aide is on “Football” duty this evening for Trump’s flight to Calgary, Canada, for the G-7 Summit. The ~45-pound satchel accompanies Trump 24/7, enabling him to authorize the use of any of our ~1,770 deployed nuclear weapons—up to 900 on alert—at any time.
