Kamala Harris Makes a Freudian Slip: "Rec"(ording) Instead of "Call"

Kamala Harris makes a Freudian Slip and almost says "recording" instead of "call" referring to Joe being on the phone. This may have just been an innocent mistake, but it makes you think - Was there supposed to be a recording? Does she communicate and listen to Biden most of the time through recordings? If so, why? It's weird at a minimum.
