For what periods of time was Barack Hussein Obama II (born August 4, 1961), the 44th and current President of the United States the president (head of a nation state) of The United States of America (commonly referred to as the United States, the U.S., the USA, or America), the federal constitutional republic comprising fifty states and a federal district?
I followed this chain of reasoning:
I know from locally stored knowledge that: Fact 1:
Barack Obamais the president ofthe United States([fact: ["firstname.lastname@example.org"]])
By calculation (generator: ["email@example.com"]) I know that: the fact firstname.lastname@example.org true for the complete timeperiodJanuary 20th 2009, 17:01 onwards
I used the following facts to provide this answer:
Barack Obama has been the president of the United States since January 20th 2009, 17:01
Barack Obama has not been the president of the United States until January 20th 2009, 17:01
