President Biden attended Mass with son Hunter on the first Sunday after he entered the White House — and then stopped on the ride back at a popular D.C. bagel joint.

The nation’s second Catholic president went to Holy Trinity Catholic Church in the Georgetown area of Washington, DC, the same church President John F. Kennedy, the country’ first Catholic commander-in-chief used to frequent.

Biden, 78, was accompanied by Hunter and Hunter’s two children, Finnegan and Maisey.

Asked about the service, Biden said it was “lovely.”

On the return trip to the White House, the presidential​ motorcade ​pulled over and Hunter Biden jumped out to make a quick run to Call Your Mother, a popular deli near the church​ known for their bagels.​

Hunter stood at the takeout window for several minutes as the president and his granddaughters remained in the limo.​​

Biden attended mass at St. Matthew the Apostle with a contingent of Democratic and Republican congressional leaders the morning of his inauguration and Vice President Kamala Harris and her husband.​
