President Donald Trump will not meet with Saudi Crown Prince Mohammed bin Salman this weekend at the G20 summit, the White House said on Tuesday.

Press secretary Sarah Huckabee Sanders said during a press briefing that although the White House has not "ruled out any interaction," the president's schedule does not allow for any additional meetings.

"I know the president's schedule is pretty packed and has a number of sessions that he will be involved in with the G20," Sanders said. "I don't think there's any time for us to add anything additional. Whether or not there's interaction, I'm not gonna rule that out."

Trump will meet with Argentinian President Mauricio Macri, South Korean President Moon Jae-in, Japanese Prime Minister Shinzō Abe and Chinese leader Xi Jinping.

He will also meet with more controversial leaders such as Turkish President Recep Tayyip Erdoğan, who has been criticized for autocratic tendencies, as well as Russian President Vladimir Putin.

National security adviser John Bolton also said during the press briefing that Trump's schedule for the G20 summit is "overflowing."

When asked whether the president will meet with the crown prince, Bolton said that he is only meeting with those previously detailed.

"The bilateral schedule is full to overflowing at this point, those are the ones I've listed that he will be meeting with," Bolton said.

The CIA has reportedly found that the crown prince was involved in ordering the murder of Washington Post columnist Jamal Khashoggi. Khashoggi, who was living in exile in the U.S. for his criticisms toward the Saudi royal family, was last seen at the Saudi consulate in Istanbul.

Trump last week released a controversial statement in which he expressed doubt about whether the crown prince was involved in the killing and said that the U.S. will continue to work with Saudi Arabia. The president also later praised low gas prices as a result of the country's relationship with Saudi Arabia.

The G20 summit is being held this weekend in Buenos Aires, Argentina.
