No final decision has been made yet, but Romney, in comparison with Gen. David Petraeus (ret) and former New York Mayor Rudy Giuliani, is in the strongest position to date.

Petraeus, sources told Garrett, is out of the running. Gen. John Kelly’s nomination to run the Department of Homeland Security played a large role: Mr. Trump will not have four generals in the upper echelons of the Trump administration — the other two are Gen. James Mattis (ret), who was named defense secretary, and Lt.-Gen. Michael Flynn (ret), who will be national security adviser. Giuliani is still on the short list, but he is not considered as likely as he once was to get the job.
