This isn’t unusual.Kamala Harris has not yet given up her senate seat. She is not convince she and Biden are going to win. I guarantee you that she knows more the inner workings than you do. There is a reason why the Dems want Trump arrested now and are panicking unable to wait for January 20. You nervous Dems?
Al Gore waited until January 2, 1993 to resign from the Senate, and Joe Biden resigned from the Senate on January 15, 2009. Mike Pence served as Indiana’s governor until January 9, 2017.
Holding her seat allows Harris to vote on Senate matters or participate in committee meetings. The Senate could conceivably consider important issues between now and Inauguration Day. No rule bars the vice-president elect from representing her state until she takes her oath on January 20.
