Stull was appointed as a Senior Advisor to the Bureau of International Organization Affairs shortly after the election of President Donald Trump. Her tenure was contentious with allegations of workplace bullying and harassment as well as undue politicization of the diplomatic service made against her. Stull reportedly engaged in six to eight hostile interactions a day at the BIOA.^[8] She objected to a legislative affairs staffer accompanying a Congressional Black Caucus trip as was standard procedure because it contained only Democrats, she reportedly personally accused the staffer of undermining President Trump’s agenda and reassigned their responsibilities.^[8]

Stull’s State Department career concluded January 11, 2019.^[5] At the time of her departure she was under investigation by an internal State Department watchdog and a US House of Representatives committee.^[9] Her actions over the course of her State Department career reportedly resulted in at least three Senior and numerous junior staff leaving the department.^[10]

In August 2019 the Office of Inspector General (United States) found that Stull and Assistant Secretary of State Kevin Moley had engaged in harassment, mistreatment, and retaliation of career state department employees.^[11] Rep. Elijah Cummings commented that Stull and Moley had violated the public trust.^[12] The report characterized the working environment under Stull and Moley to be “vindictive” and stated that “OIG found evidence of leadership and management deficiencies and mistreatment of career employees in the Bureau of International Organization Affairs. These inappropriate practices included disrespectful and hostile treatment of employees, accusations against and harassment of career employees premised on claims that they were ‘disloyal’ based on their perceived political views, and retaliation associated with conflicts of interest,” as well as retaliation against employees who refused to participate in activities over legitimate conflict of interest concerns. Stull’s former office disputed some of the actions described in the report.^[13]

Stull returned to the Inter-American Institute for Cooperation on Agriculture, assuming a position in The Bahamas.^{[18][19] [20]} Stull is a contributor to WineTasteTV.^[2] She is a senior fellow at the American Opportunity Foundation.^[21]
