A former Yale Law School classmate shared with The Times about 90 emails and text messages with Mr. Vance. Here are some of the most revealing moments in their correspondence. Nelson, now a public defender in Detroit, said the two were once close friends, but had a falling out in 2021, when Mr. Vance said publicly that he supported an Arkansas ban on gender-affirming care for minors. Now, Nelson, who opposes the Trump-Vance ticket, hopes the emails will inform the opinion of voters about Mr. Vance.
