After a federal grand jury indictment of President Trump ally Roger Stone, the top Democrat on the Senate Intelligence Committee suggested there’s more yet to become public on Stone and his involvement with Wikileaks.

“I expect that we will learn more about Mr. Stone’s campaign role, his communications regarding Wikileaks, and who else knew about Stone’s efforts,” Sen. Mark Warner (D-VA) said in a Friday morning statement.

The Senate Intelligence Committee has interviewed several top Trump allies, including Paul Manafort, the former campaign chair who was close to Stone, and Steve Bannon, who it appears was in communication with Stone about Wikileaks’ release of Democrats’ hacked emails. Those interviews and additional intelligence that the committee is privy to have not been made public.

Stone was indicted on one count of obstructing an official proceeding, five counts of false statements, and one count of witness tampering, all stemming from his alleged attempts to communicate with both Wikileaks and the Trump campaign about Democrats’ stolen emails during the 2016 campaign.
