US Vice-President JD Vance has responded to Pope Francis’s criticisms of the Trump administration's immigration policies in a speech at the annual National Catholic Prayer Breakfast held in the US capitol.

While not backing down from his more stringent immigration stance, the US vice-president was conciliatory, commending the Holy Father for his care of his spiritual flock, and praying for his health and recovery following his recent hospitalisation.

“Every day since I heard of Pope Francis’s illness, I say a prayer for the Holy Father because while, yes, I was certainly surprised when he criticised our immigration policy in the way that he has , I also know that the Pope, I believe that the Pope is fundamentally a person who cares about the flock of Christians under his leadership, and he’s a man who cares about the spiritual direction of the faith,” Vance said.
