Palmo says he believes Biden’s faith will play a role in his presidential policy.

 "Of course the Democratic Party and the church have long been at loggerheads in terms of abortion. When it comes to immigrants, when it comes to looking out for the least, when it comes a priority for the poor and working people. These are the core elements of what we call Catholic social teachings," Palmo said.

Jesuit Father Leo O’Donovan – a former president of Georgetown University – will deliver the invocation at Biden’s inauguration. 

Father O’Donovan is a friend of the Biden family, and was the main celebrant at the Mass for Biden’s son Beau in 2015 at St. Anthony of Padua Parish in Wilmington, Del.

Cardinal Wilton Gregory – the archbishop of Washington – delivered the invocation Tuesday night at a memorial service at the Lincoln Memorial to honor the 400,000 Americans who’ve died as a result of COVID-19.

Biden and Vice President-Elect Kamala Harris also participated in the event.
