President Trump has boarded Air Force One to leave the summit in Egypt.

He waved as he boarded the jet to go back to the White House.

President Trump and Canadian Prime Minister Mark Carney had a light-hearted exchange into a live microphone Monday after Trump completed his speech on Gaza to world leaders.

"I'm glad you upgraded me to 'president,'" Carney told Trump, who had given shout-outs to many visiting leaders during his remarks.

Trump grinned and replied: "At least I didn't say governor!"

Trump taunted Carney's predecessor, Justin Trudeau, by calling him "governor" of the prospective 51st state.

President Trump said in a speech to world leaders that the Gaza peace process could be his "greatest deal."

"All I've done all my life is deals. The greatest deals just sort of happen," Trump said.

"And that's what happened right here. And maybe this is going to be the greatest deal of them all."

President Trump confirmed in his remarks at the Gaza cease-fire summit that even more humanitarian aid is flowing to Palestinians.

"Humanitarian aid is now pouring in, including hundreds of truckloads of food, medical equipment, and other supplies, much of it paid for by people in this room," he said.

"Civilians are returning to their homes. The hostages are reuniting. I mean, it's beautiful," the president added. "I'm just watching it backstage. The level of love and sorrow. I've never seen anything like it."

"The rebuilding begins," Trump also said. "The rebuilding may be the easiest part. I think we've done a lot of the hardest part. We know how to build."

President Trump joked Monday that the Norwegian representative to the Gaza peace conference was hiding after the five-member Norwegian Nobel Committee snubbed him Friday by giving its prestigious peace prize to a Venezuelan opposition leader.

"We have Norway. Oh, Norway, aye aye aye! Norway, what happened? Norway, what happened?" Trump said during a celebratory speech on the peace agreement he helped broker between Hamas and Israel.

"Where's Norway? I don't think he wants to stand. Oh, he's back there."

Pakistani Prime Minister Shehbaz Sharif announced Monday that he's renominating President Trump for the Nobel Peace Prize.

"Today is one of the greatest days in contemporary history," Sharif said after Trump called him to the lectern during his own speech at the Gaza peace conference in Sharm el-Sheikh, Egypt.

"Pakistan had nominated President Donald Trump for the Nobel Peace Prize for his outstanding extraordinary contributions to first stop war between India and Pakistan and then achieve ceasefire, along with his very wonderful team," Sharif said.

"And today, again, I would like to nominate this great president for the Nobel Peace Prize, because I genuinely feel that he is the most genuine and most wonderful candidate for the Peace Prize, because he has brought not only peace in South Asia, saved millions of people their lives, and today, here in Sharm el-Sheikh, achieving peace in Gaza is saving millions of lives in the Middle East."

Sharif added: "I think that you are the man this world needed most at this point in time."

Egyptian President Abdel Fattah el-Sisi awarded President Trump the "Order of the Nile" Monday during a peace conference in Sharm el-Sheikh.

El-Sisi gave Trump his country's highest state honor in recognition of his role in the Hamas-Israel peace process.

President Trump signed the Gaza peace agreement at a conference with world leaders in Egypt.

"This took 3,000 years to get to this point, can you believe it? And it's going to hold up," Trump said as prominent leaders from Europe and the Muslim world sat arrayed behind him.

"We're doing a signing, then we're doing the speech, and then I may stay behind with the leaders, just to talk about that some things without the press," the president said, after praising various attendees, including calling Turkish President Recep Tayyip Erodgan a "tough cookie."

Trump, Erodgan, Qatari Emir Tamim bin Hamad Al Thani and Egyptian President Abdel Fattah el-Sisi signed documents on behalf of Israel and Hamas.

President Trump shook hands with a panoply of world leaders in front of a "Peace 2025" sign at a celebratory Gaza peace conference in Egypt.

Trump's photo op in Sharm el-Sheikh featured greetings with UK Prime Minister Keir Starmer, French President Emmanuel Macron, German Chancellor Friedrich Merz, Jordanian King Abdullah II, Italian Prime Minister Giorgia Meloni, Turkish President Recep Tayyip Erdogan, Canadian Prime Minister Mark Carney and others.

President Trump floated adding Egyptian President Abdel Fattah el-Sisi to the Board of Peace that is due to oversee the Gaza Strip.

"I'd like to have him on the board. I'd like to. We may need an interpreter, but that's OK. ... You can't do better," Trump said alongside el-Sisi during a joint appearance Monday.

El-Sisi, who helped facilitate peace talks between Hamas and Israel, responded through a translator that "I'll be there."

Trump is expected to chair the board, but the only other announced member is former UK Prime Minister Tony Blair.

President Trump declared "Phase 2 has started" after arriving at the Gaza peace summit in Sharm el-Sheikh, Egypt.

"Phase 2 has started. And you know, the phases are all a little bit mixed in with each other," Trump said in the resort city during an initial appearance with his Egyptian host.

"They're going to start cleaning up. You look at Gaza and it needs a lot of cleanup ... that's debris times 10."

The first phase of the peace process involved Hamas releasing 20 living Israeli hostages in exchange for the first of three Israeli troop pullbacks and the release of 250 Palestinians serving life sentences.

Additional phases following Trump's 20-point plan will feature an international peacekeeping force, the disarmament of Hamas and the appointment of a transitional government led by a Trump-chaired Board of Peace.
