Trump voiced concern but did not blame Moscow.The 24 Ukrainian sailors detained in the operation were returned last month as part of a prisoner exchange.Anderson, and his successor in the Ukraine job, Catherine Croft, both testified to House committees on Wednesday about the role played by Trump’s personal lawyer, Rudy Giuliani, in foiling state department efforts to bolster the president, Volodymyr Zelenskiy, in the face of Russian military intervention in eastern Ukraine.At the other side of Congress, the nominee to become ambassador to Russia, John Sullivan, faced pointed questions on Wednesday at confirmation hearings in the Senate about Giuliani and the split US policy towards Russia and Ukraine.Sullivan, currently the deputy secretary of state, said he was aware of Giuliani’s role in a campaign against the former US ambassador to Ukraine, Marie Yovanovitch. Asked if he knew Trump’s lawyer was “seeking to smear” Yovanovitch, he replied: “I believe he was, yes.”Sullivan confirmed he had been shown a dossier of material attacking Yovanovitch, saying it had provided by the White House to the state department legal adviser, but he was not aware it had been put together by Giuliani. He said the dossier “didn’t provide to me a basis for taking action against our ambassador”.He said that Pompeo gave Sullivan no explanation for the decision to recall Yovanovitch before the end of her posting, other than she had “lost the confidence of the president”.“As I understand, [Trump] may decide that he doesn’t like my testimony today and he doesn’t want me to go to Russia. The president can decide when he loses confidence in his ambassador – then that person is not going to continue as ambassador,” Sullivan said.Sullivan sought to avoid taking a position on the testimony by several former and current state department officials that the president, through Giuliani, had made a White House meeting and US military aid dependent on the Ukrainian government investigating Trump’s political rivals.“Soliciting investigations into a domestic political opponent – I don’t think that would be in accord with our values,” Sullivan said. But he would not confirm that was what the president had done.Democratic senators signaled that they were prepared to support Sullivan’s nomination as an experienced and respected diplomat, acknowledging the difficult position he was in. But they expressed concern he had not done more to find out what Trump and Giuliani were trying to achieve in Ukraine.The ranking Democrat on the Senate foreign relations committee, Bob Menendez, told Sullivan he had been playing the role of “see no evil, hear no evil, speak no evil.”“You’re going to go to Russia, and you’re going to be saying one set of things based upon your testimony here,” Menendez said. “And we have the president who, in his public statements, is totally aligned differently then what you’re going to be saying.”“Do you understand that the incredibly difficult job that you’re going to have as a result of that?” Menendez asked Sullivan.“I would say, senator, you’ve cited the president’s statements. I’d cite the president’s actions,” the nominee replied, listing sanctions the administration had imposed on Russia.
