During the opening day of the 2024 Republican National Convention, Donald Trump announced the selection of Sen. J.D. Vance (R-OH) as his running mate.

Trump wrote on Truth Social:

After lengthy deliberation and thought, and considering the tremendous talents of many others, 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. J.D. honorably served our Country in the Marine Corps, graduated from Ohio State University in two years, Summa Cum Laude, and is a Yale Law School Graduate, where he was Editor of The Yale Law Journal, and President of the Yale Law Veterans Association. J.D.’s book, “Hillbilly Elegy,” became a Major Best Seller and Movie, as it championed the hardworking men and women of our Country. J.D. has had a very successful business career in Technology and Finance, and now, during the Campaign, will be strongly focused on the people he fought so brilliantly for, the American Workers and Farmers in Pennsylvania, Michigan, Wisconsin, Ohio, Minnesota, and far beyond….

Earlier Monday it was reported that there was extra security posted at Vance's Ohio home, and that he'd left in a motorcade for the Republican National Convention in Milwaukee, leading to speculation that Vance would be Trump's pick.
