As I explained in another answer Yovanovitch was fired for stonewalling Ukranian government officials visa requests (which deeply hurt or relations with Ukraine) and alleged obstruction of justice.
Trump said this about her: during the infamous phone call.
“The former ambassador from the United States, the woman, was bad news and the people she was dealing with in the Ukraine were bad news,” Trump said in their July 25 conversation, according to a transcript released by the White House. “She’s going to go through some things.”
Kostiantyn Kulyk, deputy director of Ukraine’s Prosecutor General’s International Legal Cooperation Dept., told John Solomon that for over a year he and a team of senior officials has been blocked by Yovanovitch from getting visas to go to the U.S. to testify to Democratic party perfidy and lawbreaking.
We were supposed to share this information during a working trip to the United States,” Kulyk told me in a wide-ranging interview. “However, the [U.S.] ambassador blocked us from obtaining a visa. She didn’t explicitly deny our visa, but also didn’t give it to us.”
In another instance, he said, Ukrainian authorities gathered evidence that money paid to an American Democrat allegedly was hidden by Ukraine’s National Anti-Corruption Bureau (NABU) during the 2016 election under pressure from U.S. officials. “In the course of this investigation, we found that there was a situation during which influence was exerted on the NABU, so that the name of [the American] would not be mentioned,” he said.
Other items mentioned in the report:
- Sworn statements from two Ukrainian officials admitting that their
agency tried to influence the 2016 U.S. presidential election in
favor of Hillary Clinton. The effort included leaking an alleged
ledger showing payments to then-Trump campaign chairman Paul
- Contacts between Democratic figures in Washington and Ukrainian officials that involved passing along dirt on Donald Trump;
- Financial records showing a Ukrainian natural gas company routed more
than $3 million to American accounts tied to Hunter Biden, younger
son of then-Vice President Joe Biden, who managed U.S.-Ukrainian
relations for the Obama administration. Biden’s son served on the
board of a Ukrainian natural gas company, Burisma Holdings;
- Records that Vice President Biden pressured Ukrainian officials in
March 2016 to fire the prosecutor who oversaw an investigation of
Burisma Holdings and who planned to interview Hunter Biden about the
- Correspondence showing members of the State Department and U.S.
embassy in Kiev interfered or applied pressure in criminal cases on
- Disbursements of as much as $7 billion in Ukrainian
funds that prosecutors believe may have been misappropriated or
taken out of the country, including to the United States.
Trump evidently believed that set of facts, citing the story above directly.
