Robert Harward turns down national security adviser position

Trump has to fill the vacancy left by Mike Flynn, who resigned Monday.

Harward, an ABC News contributor, and Trump had spoken recently about a position in the administration, according to the officials.

But after weighing the opportunity of national security adviser, Harward cited his family in declining the job, the senior administration official said.

"I was humbled and honored," Harward told ABC News, but said of the job, "It takes 24 hours a day of focus... It's a tough sacrifice" and after 40 years of military service, he was not ready to come back from retirement.

Harward denied turning down the offer because of chaos in the West Wing.

"I have somebody that I think will be outstanding for the position," President Trump said Thursday at a White House press conference.

Thursday evening, reaction to Harward's decision was already coming in.
