Trump gave Pope Francis a special edition of the works of civil rights icon Martin Luther King Jr.
UPDATE 8:24 a.m. EST: Trump tweeted that the meeting was the "Honor of a lifetime."
President Trump finally met face-to-face with Pope Francis on Wednesday in Vatican City after the two exchanged indirect criticism during the 2016 presidential campaign, reports CNN.
And while the pair made less than sterling comments about each last year, their meeting this week was very amicable.
"Thank you. I won't forget what you said," Trump said after an hour-long private meeting with the pope in his study.
While neither Pope Francis nor Trump revealed what it was they discussed in the meeting, a statement released by the Vatican said that the two men discussed "the promotion of peace in the world through political negotiation and interreligious dialogue."
"We had a fantastic meeting. We're liking Italy very, very much and it was an honor to be with the Pope," said Trump of Pope Francis.
Unfortunately, the meeting has been the subject of some derision on Twitter.
