Vice President J.D. Vance questioned on Monday whether former President Joe Biden was “capable of doing the job” of Commander in Chief, following the news that Biden has an aggressive form of prostate cancer.

The moment comes after Vance allegedly broke Vatican protocol when he took a trip to the grand Sistine Chapel, famously home to Michelangelo's sprawling religious painting of nine scenes from the Book of Genesis and where the papal conclave holds its secretive election meetings.

Their meeting signalled the Vatican’s diplomatic influence under the new Pope and its potential to act as a venue for peace talks between Russia and Ukraine.

Leaders and common people flocked to St Peter's Basilica at the Vatican to listen to Pope Leo's inaugural mass.
