The tensions came to a head around the time President Donald Trump delivered a politicized speech in late July to the Boy Scouts of America, an organization Tillerson once led, the officials said.

Just days earlier, Tillerson had openly disparaged the president, referring to him as a “moron,” after a July 20 meeting at the Pentagon with members of Trump’s national security team and Cabinet officials, according to three officials familiar with the incident.

While it's unclear if he was aware of the incident, Vice President Mike Pence counseled Tillerson, who is fourth in line to the presidency, on ways to ease tensions with Trump, and other top administration officials urged him to remain in the job at least until the end of the year, officials said.

The petty humiliations they inflict on each other will, one day, be quite funny.
