Trump did receive a 4 gun salute outside the capital and biden did receive a 3 gun salute at the Arlington Cemetery.

>3 Guns for visiting foreign dignitaries/funerals

HWB got a 4 gun salute outside the capital (with 1 misfire) fired in slow succession similar to bidens shot cadence.

Can any anon provide information on why bush got 4?

Is it typical that a 21 gun salute is done at Arlington when POTUS visits?
