Washington (CNN) Rudy Giuliani told CNN that President Donald Trump has been "very supportive" of his continued efforts to dig up dirt on Democrats in Ukraine, including his most recent trip to the Eastern European country.

The admission bolsters a central Democratic argument of the impeachment proceedings: that the President has allowed his personal attorney to push Ukraine for investigations that benefit Trump's political agenda.

In a phone conversation with CNN on Tuesday, Giuliani suggested that Trump has been well aware of everything he has done in Ukraine, though he declined to say if Trump directed him to go on his most recent trip there.

"We're on the same page," Giuliani said of Trump.

Visiting Ukraine earlier this month, Giuliani claims he gathered evidence of a wide-ranging conspiracy to prevent his and the President's efforts to uncover years of corruption there. In Giuliani's view, that corruption chiefly involves Trump's domestic political opponents, including Joe Biden as well as Hillary Clinton.
