Janet Napolitano, who was handpicked by President Barack Obama to defend America's borders, allegedly allowed a female subordinate to terrorise some of the country's most senior security officials while moving less-experienced women to top roles.
The lawsuit alleges that Suzanne Barr, Miss Napolitano's chief of staff at Immigration and Customs Enforcement (ICE), would regularly carry out "sexually offensive" behaviour intended to "humiliate and intimidate male employees".
On one occasion Miss Barr allegedly called a male staffer in his hotel room one a work trip and screamed sexual abuse down the phone at him, telling him she wanted to perform oral sex on him.
