Sean Spicer, devout Catholic, didn't get to meet the Pope.
Pope Francis also gave Mr Trump a signed copy of his 2017 peace message whose title is Nonviolence - A Style of Politics for Peace, and a copy of his 2015 encyclical letter on the need to protect the environment from the effects of climate change. The pope also gave Trump a medallion depicting an olive branch as a symbol of peace.
"I didn't know that Melania was going to be saying the Lord's Prayer, but I thought that was handsome, thank you", the president said immediately after, according to CNN. This time, Melania Trump covered her head with the black headscarf.
Later, as he met with the Italian Prime Minister Paolo Gentiloni, Trump said of the pope: "He is something".
Following the meeting, Scavino posted a photo of Trump's delegation and the pontiff on his own Twitter account, writing: "THANK YOU Holy Father Pope Francis".
After arriving in Brussels - a city he called a "hellhole" while campaigning in 2016 - Trump met with Michel and said "we will win, 100%" in the fight against terrorism.More news: FA Cup win won't disguise poor season, says Welbeck

Mr Trump and the Pope were famously at loggerheads previous year, when the former said building a wall - the one proposed between the United States and Mexico - would show Mr Trump was "not a Christian". But the first lady's clothing choices - specifically her decision to cover her head at the Vatican in contrast to during visits to Saudi Arabia and Israel - drew commentary from many sources.
Both sides agreed to limit the number of staffers attending the high-profile meeting, according to CNN, and President Donald Trump's entourage included mostly family.
There's been a lot of attention on Donald Trump's hands during his first foreign trip as United States president.
"A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian".
The pope asked her, through a translator: "What do you give him to eat, potizza?".
After photos from President Trump's visit to the Vatican began circulating, there nearly wasn't any need for comedians to make light of the situation.
