Saudi Arabia's new king is skipping an upcoming summit of Persian Gulf states being hosted by President Barack Obama, which has led many critics to speculate that Obama is being snubbed. 

Of the six invited nations, Kuwait and Qatar are the only two who are sending monarchs to attend the summit. 

Saudi Foreign Minister Adel al-Jubeir said in a statement that King Salman bin Abdulaziz Al Saud could not attend the summit, because it coincides with a humanitarian cease-fire in Yemen.

During a number of press briefings today, the Obama administration scrambled to try and downplay the situation. 

Fox News reported:

...State Department spokeswoman Marie Harf rejected the notion this was a "snub," and White House Press Secretary Josh Earnest likewise said the administration is "confident" that Saudi Arabia and other nations will be "ably represented" at the summit.

Earnest confirmed Monday that Saudi King Salman would no longer attend, noting the king originally had accepted the invitation. But Earnest stressed that Saudi Arabia did not express any concerns to the U.S. before or after the Saudi king's change in travel plans.

Deputy national security adviser Ben Rhodes said Monday afternoon Obama and the King had spoken earlier in the day. He added they also had spoken recently and would continue their dialogue despite the King opting out of the summit.

Earnest said the feedback the U.S. has had from Saudi Arabia has been "positive," and as for speculation that Riyadh might have been trying to send a message to the Obama administration with the change, Earnest said: "If so, that message is not received."

On "Special Report" tonight, Charles Krauthammer said that a "loud statement" is being sent by the leaders who have opted out of attending the summit. 

"This isn't about geriatric travel problems," Krauthammer stated. "This is a loud statement from the gulf states. You don't have to be an expert. You have to be about 11 or older to understand what this statement is."

He said that the cease-fire in Yemen is not the reason why the leaders are not attending Obama's summit. Krauthammer stated that this has to do with Iran's nuclear deal. 

"This is a rejection of the agreement that the United States is about to embark in with Iran by the states who are going to be very badly affected by and strongly object to it," Krauthammer said.
