There are the rules on the books and then there is what they actually do in practice
For example the President is not supposed to make laws
But Presidents promise laws like Obama Care and the Congress does not seem to say it is none of your business we will make our own decision President but go along with what the President suggests if they are of the same political party
Presidents have started wars even though only Congress is supposed to have that authority
But if the people choose to ignore the time limits then the time limits will be ignored
My suspicion at this point is that if Kamala Harris wants a rule to be broken then it will be broken
