Eisenhower threatens reporters

[snopes]

Comment: Actually, I heard about this many years ago, but cannot find any
evidence to support whether this actually happened. I would like to
believe the story is true!

During WWII, before D-Day, the newspapers, in trying to figure out what
America was going to do, were getting dangerously close to guessing the
actual assault that was being planned. General Eisenhower called a
meeting with representatives from all the newspapers in attendance. When
the representatives entered the room, all pens and notepads were removed
from their possession so they couldn't take notes.

General Eisenhower then outlined the entire invasion. When he concluded,
he said:

"Gentlemen, you now know the entire plan. If you print one word of this,
you will be guilty of treason and you will be shot."

Then he left the room. From that time on, no more mention was made of
possible targets.

IS THIS TRUE?
