President Donald Trump appeared moved by his private meeting with Pope Francis, telling the pope that he "won't forget what you said."
The president and pope have a contentious history and disagree on a host of issues, including environmental protection.
The White House did not immediately provide details about what was discussed during their 30-minute private conversation. But the two men appeared on good terms Wednesday, including during a traditional gift exchange.
The pope's gifts to Trump included a medal by a Roman artist depicting an olive, which is a symbol of peace.
The president responded, "We can use peace."
The pope also gave the president a signed message of peace along with copies of his three main teaching documents.
The president told the pope he'd be reading them.
