Robert Fico, one of the few EU leaders to frequently support Trump’s stance on Europe’s weaknesses, was concerned about the U.S. president’s “psychological state,” two of the diplomats said. Fico used the word “dangerous” to describe how the U.S. president came across during their face-to-face meeting at Trump’s Mar-a-Lago estate in Florida on Jan. 17, according to two of the diplomats.

Fico seemed to be “traumatized” by his encounter with Trump, one of the European diplomats said. Fico characterized Trump as being “out of his mind,” a diplomat said, using the words briefed to them by their leader, who was directly involved in the conversation.
