Use the author's last name and the year inside parenthesis.
Jefferson traveled to France to be the ambassador for the United States (Foster, 2014).
If you've mentioned the author already you only need the year.
Foster writes about Jefferson's travels to France and the work he did with that population in securing deals for the new United States (2014).
