The Facts

• The now-official Republican presidential nominee Donald Trump named Sen. JD Vance of Ohio as his running mate on Monday at the Republican National Convention in Milwaukee.

• The former president stressed that Vance was "the person best suited" to the position and would focus on "the American Workers and Farmers in Pennsylvania, Michigan, Wisconsin, Ohio, Minnesota and far beyond" on the campaign trail.

• Once a fierce Trump critic, the 39-year-old changed his position ahead of the 2022 Senate race and has become one of his staunchest supporters in the upper chamber.
