The arrival of the baby, a boy, will mark the first time in modern history a second lady has given birth while her husband is serving as vice president.
William D. DeFoor, 26, faces federal and local charges stemming from the alleged vandalism in Cincinnati. Vance and his wife were in Washington, D.C., when the incident unfolded.
At the Turning Point USA conference in Phoenix last week, the vice president was a heavy favorite, securing the endorsement of CEO Erika Kirk and winning a straw poll of attendees.
Charlie Kirk's widow consoled the mortified rapper after the unfortunate remark: "Trust me, there's nothing new under the sun that I have not heard, so you're fine."
The widow of Turning Point USA co-founder Charlie Kirk threw the organization's support behind the vice president, who hasn't yet announced his 2028 plans.
In an interview with NBC News, the vice president covered a wide range of topics, including his thoughts on high prices, 2028 and Democrats he appreciates.
