President Donald Trump's lawyer Rudy Giuliani said in a new interview that the arrest of WikiLeaks founder Julian Assange could uncover details of a Ukrainian plot against Trump and Russia.

"Maybe it will shed light on the plot to create an investigation of President Trump based on a false charge of conspiracy with the Russians to affect the 2016 elections. Keep your eye on Ukraine," Giuliani told the Washington Examiner.

"It's possible with all his sources he might know or have information of how it all started."

Giuliani's remarks came one day after Assange was arrested following his ouster from the Ecuadorian embassy in London, where he had been holed up since 2012. He was indicted on charges that he helped Chelsea Manning steal hundreds of thousands of classified documents from U.S. government computers.

Giuliani told the Examiner he thinks Assange might have information that would "show who invented [the] false story that [Trump] colluded with Russians."

Some have alleged that Assange worked with the Russians to obtain stolen emails and documents from the Democratic National Committee during the 2016 campaign. Assange, however, claims Russia was not his source.
