Not out of the question, per the NYT:
The Trump team’s efforts to draw attention to the Bidens’ work in Ukraine, which is already yielding coverage in conservative media, has been led partly by Rudolph W. Giuliani, who served as a lawyer for Mr. Trump in the investigation by the special counsel, Robert S. Mueller III. Mr. Giuliani’s involvement raises questions about whether Mr. Trump is endorsing an effort to push a foreign government to proceed with a case that could hurt a political opponent at home.
Mr. Giuliani has discussed the Burisma investigation, and its intersection with the Bidens, with the ousted Ukrainian prosecutor general and the current prosecutor. He met with the current prosecutor multiple times in New York this year. The current prosecutor general later told associates that, during one of the meetings, Mr. Giuliani called Mr. Trump excitedly to brief him on his findings, according to people familiar with the conversations.
Mr. Giuliani declined to comment on any such phone call with Mr. Trump, but acknowledged that he has discussed the matter with the president on multiple occasions. Mr. Trump, in turn, recently suggested he would like Attorney General William P. Barr to look into the material gathered by the Ukrainian prosecutors — echoing repeated calls from Mr. Giuliani for the Justice Department to investigate the Bidens’ Ukrainian work and other connections between Ukraine and the United States.
Mr. Giuliani said he got involved because he was seeking to counter the Mueller investigation with evidence that Democrats conspired with sympathetic Ukrainians to help initiate what became the special counsel’s inquiry.
