Secretary of State Rex Tillerson was having dinner at a local restaurant when the owner came over to tell him that Mexico’s foreign secretary happened to be eating at the same place. Would he like to say hello?

Tillerson was surprised, he recently recounted to congressional aides, because he hadn’t been informed that his Mexican counterpart, Luis Videgaray Caso, was in Washington, D.C. He walked over to find that Jared Kushner, President Donald Trump’s son-in-law and senior adviser, was dining with the foreign diplomat.

“I could see the color go out of the face of the foreign secretary of Mexico as I very — I smiled big, and I said: ‘Welcome to Washington,’” Tillerson told the staffers. “And I said: ‘I don’t want to interrupt what y’all are doing.’ I said: ‘Give me a call next time you’re coming to town.’ And I left it at that.”
