She was US ambassador to Ukraine during the 2016 election when the Ukrainian government was colluding with the DNC and Hillary Campaign to undermine the US presidential election.
Starting in 2018 Yovanovich denied Ukrainian officials visas to enter the United States to hand over evidence of Obama administration misconduct to Trump administration officials.
US Ambassador Yovanovich, an Obama appointee, was removed from her post in Ukraine early in May 2019.
John Solomon at The Hill reported:
According to interviews with more than a dozen Ukrainian and U.S. officials, Ukraine’s government under recently departed President Petro Poroshenko and, now, Zelensky has been trying since summer 2018 to hand over evidence about the conduct of Americans they believe might be involved in violations of U.S. law during the Obama years.
The Ukrainians say their efforts to get their allegations to U.S. authorities were thwarted first by the U.S. embassy in Kiev, which failed to issue timely visas allowing them to visit America.
