Washington (CNN) Former Director of National Intelligence James Clapper predicted Friday there will be "other shoes to drop" in special counsel Robert Mueller's investigation into Russian meddling in the 2016 US election.

"I think there are other shoes to drop here, notably the finances," Clapper said on "Anderson Cooper 360."

Although he admitted that he did not know for sure, Clapper said that following the indictments announced in the probe Friday, more information about President Donald Trump's financial assets could potentially come out from the investigation.

"I think that's going to be another profound thing that's going to come out about this. What were the financial relationships between the Trump Organization before the election and then the Trump campaign?" Clapper said.
