US Secretary of State Marco Rubio is scheduled to visit Rome and the Vatican this week, according to an Italian government source. The trip comes at a time of heightened tension between US President Donald Trump and Pope Leo XIV over war and migration policies. During the visit, Rubio is expected to meet Vatican Secretary of State Cardinal Pietro Parolin and Italian Foreign Minister Antonio Tajani, and may also meet Defense Minister Guido Crosetto. Italian media have described the visit as a diplomatic effort to 'warm relations.'

The tensions trace back to May 2025, when Pope Leo XIV, who succeeded Pope Francis, criticized the Trump administration’s immigration stance and expressed concern over US-Israel threats toward Iran. Trump responded by calling the Pope 'weak' and rejecting his views on Iran and nuclear issues. Italian Prime Minister Giorgia Meloni also condemned Trump’s remarks, prompting Trump to accuse Italy of insufficient NATO support and to threaten troop withdrawals from Italy, Spain, and Germany.

The visit is seen as an attempt to ease strained relations between Washington, the Vatican, and European allies following months of diplomatic friction.
