Saudi billionaire investor Prince Alwaleed bin Talal told CNBC on Thursday he's optimistic about the U.S. economy after the surprise election of Donald Trump, saying the president-elect would likely be different in office than as a candidate.



"There's no excuse at all for the Republican Party, which is dominant in the United States, to not deliver this growth that is expected from them," Alwaleed said in a telephone interview with "Squawk on the Street."

Not only did Trump win the presidential election, but his party maintained majorities in both chambers of Congress.



"One of the concerns that world leaders have against — I emphasize candidate Trump, not president Trump — is that they were not sure about his commitment to all of the international treaties that he had," the Saudi billionaire said.
