Nice try, but Covid in the US has next to nothing to do with Biden.Bluster dear LAX, just bluster. Biden needs a distraction from the low numbers of vaccine take-up in some areas, so blame, ummm, the UK!!
Vaccine orders and Operation Warp-speed were under Trump administation and the Democrat controlled Congress.
Vaccine implementation and lockdowns/ mask mandates are the sole power of state (and in some states municipal) governments.
Literally the only real powers Biden has on the matter are over immigration restrictions and on things like mask mandates in Federal buildings.
Most airlines are offering flexible conditions and many hotels are generally quite flexible even in normal times. You might want to check the exact conditions and deadlines though.I wasn’t planning on booking anything at all but the wife had other ideas. She assures me it is all fully refundable if unable to travel.
