From The Washington Post, reporting on a May 17 Coast Guard Academy graduation ceremony:

During the commencement, Trump was presented with a ceremonial saber. After accepting it to applause, he returned to his seat next to Secretary of Homeland Security Gen. John F. Kelly.

Smiling, Kelly leaned over the president and said, of the saber, “You can use that on the press.”

“Yeah, that’s right,” said Trump, as Kelly laughed.

And then, the very next day, Gen. Kelly met with the foreign minister and interior minister of Mexico, where at least six journalists have been murdered since early March.
