U.S. PRESIDENT | Line of Succession

The photos are as of August 2017. They omit #9, Sonny Perdue (R), Agricultue Secretary.
The wrong person is also listed as #11, Secretary of Labor; it should be Alex Acosta (R).

Acting officers whose prior appointment required Senate confirmation are considered eligible for the line of succession. 

No Democrats or women appear among the top 14 names on this list. The highest-ranking woman on the list would have been Elaine Chao (R), Secretary of Transportation, at  #14, except that she is a naturalized, not a natural-born, citizen.

Postscript, April 28, 2020: The first in line after Mike Pence would now be Nancy Pelosi.
