Any US citizen can be elected speaker what is GEOTUS is announcing in a week once the votes are confirmed that he will throw his hat on the ring to be speaker.
Then if the president and veep are removed for say treason he finishes their terms little less than two years and can run again in 24 even without debating 2020 results
Interesting coincidence because I am expecting Biden serious fuk up right after it. 666 days since "inauguration" is on Nov 16.
Or Nov 17 if you count the day.
