The Qatari crisis isn't the first time Trump's winks and nods precipitated trouble.
After "examining the cause" of the crisis, the Jordanian government also chose to revoke licenses for the Doha-based broadcaster Al Jazeera.
Sabah left Tuesday night for Saudi Arabia, where he met with King Salman. Trump's administration was going to be a mediator between Saudi Arabia and Qatar.
For the tiny, oil rich nation of Qatar, Al Udeid Air Base, home to more than 10,000 US service members, has always been something of an insurance policy.
Saudi Arabia's central bank advised banks in the kingdom not to trade with Qatari banks in Qatari riyals, banking sources said. On Tuesday, he endorsed Saudi-led actions against Qatar in a tweet that amounted to self-praise for his speech in Saudi Arabia on May 21, which embraced a pro-Saudi view of the Middle East. U.S. Secretary of State Rex Tillerson said the move was rooted in longstanding differences and urged the parties to resolve them.
Exxon Mobil Corp said on Tuesday that production and exports of liquefied natural gas from Qatar have not been affected by rising diplomatic tensions in the Middle East.
Another question was whether the mounting crisis would impede regional unity on fighting the Islamic State group and other extremist threats in the region, although U.S. military and diplomatic officials have thus far insisted they anticipate no change to cooperation on those efforts. "Donald Trump now accepts the view of Saudi Arabia as a strategic bastion in the Arab and Islamic world", Fawaz Gerges, a professor of Middle East studies at the London School of Economics, told The Washington Post.
A State Department official says the US believes it is most effective for countries in the region to resolve the conflict among themselves.

Maersk, the world's biggest container shipping line, said it was unable to transport goods in or out of Qatar because it could not take them through the UAE port of Jebel Ali.
The move came just two weeks after U.S. President Donald Trump visited Saudi Arabia and vowed to improve ties with both Riyadh and Cairo to combat terrorism and contain Iran.
Make no mistake, Qatar has always upheld its sovereign right to charter a foreign policy course and ultimately shape its destiny independently. On the one hand, it could simply bow to Saudi and Emirati pressure once again; on the other, it could continue to chart its own course independent of the other GCC countries, moving closer to Iran and keeping up its support for Islamists.
Qatar has also been criticised for supporting Islamist rebels in Syria, and in 2013, the Afghan Taliban opened a Doha office. Those nations are also evicting all Qatari citizens.
