text:  Live from NPR News in Boston, I'm Steve Brown. Former President Donald Trump has chosen Ohio Senator J.D. Vance as his vice presidential pick. In a post on Truth Social today, Trump posted, quote, I have decided that the person best suited to assume the position of vice president of the United States is Senator J.D. Vance of the great state of Ohio. Vance's selection as Trump's VP comes as the Republican Party leans into the former president's MAGA messaging campaign.
