Pompeo tries to boost morale in first remarks to State Department employees

Pompeo made no mention of his fired predecessor Rex Tillerson.

"The U.S. diplomatic corps needs to be in every corner, every stretch of the world, executing missions on behalf of this country, and it's my humble noble undertaking to help you achieve that," Pompeo said.

Pompeo emphasized the learning curve he faces. He jokingly told a story about advice he received from a platoon sergeant during his early military career: “You’ll do well to just shut up for a while.” Pompeo said he plans to lay out his leadership style and his expectations for State within the next week or so. Pompeo got a generally warm reception with employees applauding and laughing at his jokes.

About his leadership style, Pompeo said "this is very different. One of my first rules is 'don't talk down to people.'"

"That’s a pretty tough combination to face as an opponent but the good news for us is he’s coming here to lead our team," Sullivan said.

Pompeo was also flanked by his wife, Susan.

"I think I have the record for the longest trip to the first day of work," Pompeo said.
