CNN's Jake Tapper compares Trump's tweet on Bette Midler to Eisenhower before D-Day -- it didn't go well for the president

CNN anchor Jake Tapper received a jolt on Tuesday with two diametrically opposed views on leadership.

President Donald Trump engaged in a 1:30 a.m. local time Twitter feud with actress Bette Midler.

Tapper had been reading about former Supreme Allied Commander Dwight Eisenhower and D-Day, prior to the battle's 75th anniversary on Thursday.

"I just spent an hour reading about Eisenhower the day before D-Day. Reading this tweet after that hour was like jumping into a lake in the middle of winter," Tapper noted.
