July 19 (UPI) — Second lady Usha Vance gave birth Sunday to her fourth child, JD Vance announced, making him the first sitting vice president in more than 150 years to welcome the birth of a child.

“We are excited to announce that our baby boy, Alec Neel Vance, was born this morning,” JD said in a statement.

“Usha and the baby are happy and healthy, and our kids are overjoyed to meet their little brother.”

The Vances have three other children: two sons, Ewan and Vivek, ages 9 and 6, respectively; and a 4-year-old daughter, Mirabel.

“The incredible military doctors and staff members of Walter Reed [National Military Medical Center] and the White House Medical Center and the White House Medical Unit have been a blessing,” JD continued.

“We are deeply thankful for all they have done for our family.”

Usha — a lawyer who resigned from Munger, Tolles & Olson on the day her husband was tapped to be Donald Trump’s running mate in 2024 — announced her fourth pregnancy in January with a due date of late July.

With the birth, the Vances became the first vice presidential couple to welcome a child while in office since Vice President Schuyler Colfax’s wife, second lady Ellen Maria Colfax, gave birth to Schuyler Colfax III in 1870.
