Donald Trump opened his first presidential foreign trip in Saudi Arabia on Saturday and won a warm reception as he looked to shift attention from a political firestorm over his firing of former FBI Director James Comey.
Saudi King Salman bin Abdulaziz greeted him on a red carpet as he stepped off Air Force One, shaking the hand of his wife, Melania, and riding in the U.S. presidential limousine.
It was a warmer welcome than had been granted last year to Trump's predecessor, Barack Obama, who was seen in the Arab kingdom as soft on Iran and hesitant on Syria.
Trump's trip to Saudi Arabia, Israel, Italy, the Vatican and Belgium has been billed by the White House as a chance to visit places sacred to three of the world's major religions, while giving Trump time to meet with Arab, Israeli and European leaders.
But the uproar in Washington cast a long shadow over the trip. The president's firing of Comey and the appointment of a special counsel to investigate his campaign staff's alleged ties to Russia last year have triggered a stream of bad headlines.
The New York Times reported Trump had called Comey a "nut job" in a private meeting last week in the Oval Office with Russian Foreign Minister Sergei Lavrov and ambassador to the United States Sergei Kislyak.
The White House did not deny the report, but said "the real story is that our national security has been undermined by the leaking of private and highly classified conversations."
In another development, The Washington Post said a current White House official close to Trump was a significant "person of interest" in the investigation into possible ties between Trump's presidential campaign last year and Russia.
Trump and King Salman seemed at ease with each other, chatting through an interpreter. At the royal al-Yamama palace, the king decorated Trump with the King Abdulaziz medal, the country's top civilian honor.
The king was overheard lamenting the Syrian war to Trump, who ordered air strikes against a Syrian airfield in April in response to a chemical weapons attack by government forces against civilians.
"Syria too used to be one of the most advanced countries. We used to get our professors from Syria. They served our kingdom. Unfortunately, they too brought destruction to their own country. You can destroy a country in mere seconds, but it takes a lot of effort," he said.
Trump's response could not be heard.
The two leaders exchanged tweets, Trump saying it was great to be in Riyadh. King Salman said Trump's visit would strengthen strategic cooperation.
Trump's decision to make his first official trip abroad to Saudi Arabia, followed by Israel, countries which both share his antagonism toward Iran, marks a contrast with Obama's approach.
Trump's criticism of the nuclear deal Iran reached with the U.S. and five other world powers in 2015 pleases both Saudi Arabia and Israel, who accused Obama on "going soft" on Tehran.
Poll results showed on Saturday that Iranians had emphatically re-elected President Hassan Rouhani, architect of Iran's still-fragile detente with the West.
After a royal banquet, Trump and the king were to have private talks and participate in a signing ceremony for a number of U.S.-Saudi agreements, including a $100 billion deal for Saudi Arabia to buy American arms.
U.S. technology and engineering conglomerate GE said on Saturday it had signed $15 billion of business deals with Saudi Arabia as part of the kingdom's drive to diversify its economy beyond oil.
The Kingdom was also due to sign a deal that includes a pledge to assemble 150 Lockheed Martin Blackhawk helicopters in Saudi Arabia, an official statement about the deal said, in a $6 billion deal expected to result in about 450 jobs in the kingdom.
National oil giant Saudi Aramco was also expected to sign $50 billion of deals with U.S. companies on Saturday, part of a drive to diversify the kingdom's economy beyond oil exports, Aramco's chief executive Amin Nasser said.
Trump is to deliver a speech in Riyadh on Sunday aimed at rallying Muslims in the fight against Islamist militants. He will also attend a summit of Gulf leaders of the six-member Gulf Cooperation Council.
Ahead of Trump's trip, the White House said the president expected tangible results from Saudi Arabia in countering Islamic extremism.
Shortly after taking office, Trump sought to temporarily halt immigration from six Muslim-majority nations from entering the United States, but the travel ban has been blocked by federal courts.
The 70-year-old president's trip to Saudi Arabia, Israel, Italy and Belgium will be Trump's longest time away from the White House since he took office four months ago.
Even his hand gestures may draw scrutiny in the Middle East, where the thumbs-up sign, a Trump trademark, is considered taboo.
