Joe Scarborough, co-host of MSNBC's "Morning Joe," has implied that President Donald Trump is not a Christian just before a discussion about the leader's recent meeting with Pope Francis.

After the hosts of the show spent some time discussing Trump's proposed budget, co-host Mika Brzezinski introduced the next segment on the president's meeting with the pope.

"They didn't actually see eye to eye during the presidential campaign, so what happened during Donald Trump's meeting today with Pope Francis? We'll go through that and what drove them apart in the first place," said Brzezinski, just before the show went on a commercial break.

When Brzezinski finished speaking, Scarborough appeared to criticize Trump, suggesting that he is not a Christian. "Oh, the Pope's Christian," said Scarborough, who appears to be hinting at the differences between Trump and the pope.

Scarborough, a former Republican congressman, had been an outspoken critic of Trump and had often referred to the president as a Democrat because of his track record of changing political parties.

The MSNBC host was not the first person to question the faith of Trump, who identifies as a Presbyterian.

The pope himself had criticized Trump during the 2016 presidential campaign for his plan to put up a border wall along the U.S.-Mexican border.

"A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian. This is not the gospel," Francis said, as reported by AOL News.

Trump immediately responded by saying, it was "disgraceful" for a religious leader to question another man's faith. The Vatican later clarified that the pope's remarks were not a personal attack against Trump.

During their meeting on Wednesday, the pope and the president spoke in private for 30 minutes and vowed to fight together for life, peace and religious freedom.

"Honor of a lifetime to meet His Holiness Pope Francis. I leave the Vatican more determined than ever to pursue PEACE in our world," Trump tweeted after the meeting.

The pontiff presented the president with a split medallion held together by an olive tree, symbolizing peace. Trump, on the other hand, gave Francis a box containing five of Martin Luther King Jr.'s books, including a signed copy of The Strength to Love.

The Vatican stated that the two leaders expressed their hope that they can collaborate "in service to the people in the fields of healthcare, education and assistance to migrants."
