If Joe Biden is removed by 25th Ammendment, then Kamala "Heels Up" Harris obviously becomes President. By law, she then appoints someone to fill her old position. This is subject to congressional approval.
The 25th Amendment states: “Whenever there is a vacancy in the office of the Vice President, the President shall nominate a Vice President who shall take office upon confirmation by a majority vote of both Houses of Congress."
Since this is all a big show, and the end is not for everyone... I bet I know who will be chosen and the surprise ending.
Kamala will choose Hillary Clinton as her V.P.
Hillary Clinton will quickly betray Kamala, conspire with the staff and remove her using the 25th Ammendment, making Hillary Clinton president. She will then announce Nancy Pelosi as her Vice President. The nation will see Hillary / Pelosi in the White House with pedophile rapist Bill Clinton returning as first "gentleman" .
Michelle ?
