Trump has spoken privately about his fears over risks to his own life, according to a former senior White House official, who has discussed the issue with the president and spoke on the condition of anonymity to speak candidly about Trump’s concerns.

“He’s never been interested in going,” the official said of Trump visiting troops in a combat zone, citing conversations with the president. “He’s afraid of those situations. He’s afraid people want to kill him.”

Pressure for Trump to make such a visit has been building for months. Eliot Cohen, a former George W. Bush administration official and Trump critic, has raised the issue regularly in public.

“The point is American servicemen and women are on the ground in these places,” Cohen said in an interview. “They are getting killed. I think any good leader would want to see something for themselves. And they would want to do something for the troops other than using them as props.”
