Unnamed sources told The Daily Mail that she has a hand in managing the defense secretary's activities and public image. "Now there's a woman with an extremely tight leash on the man she married," one source told the outlet. "She's like his parole officer and PR agent all at once," another source previously said. Her degree of influence, the sources suggested, has prompted a derisive comparison among some staffers. They have reportedly dubbed her "Yoko Ono" after John Lennon's widow, who was often portrayed by critics as a controlling influence on the late Beatles superstar. A narrative has also persisted for decades that she was the reason the band broke up.
