Washington reporter Keith Boag takes an in-depth look at the Mueller investigation evidence and what we know so far.
Schiff's comments Sunday come as Democrats have made it clear that they are ready for an aggressive, public fight with the Justice Department if they are not satisfied with the level of access they have to Mueller's findings.
But Democrats have said they are concerned Attorney General William Barr will withhold key portions of the report. "So I think there'll be huge pressure not only on the department, but on the attorney general to be forthcoming".
Special Counsel Robert Mueller's team told a United States judge on Saturday that President Donald Trump's former campaign chairman Paul Manafort "repeatedly and brazenly" broke the law, and did not deserve leniency.
Other Democrats have threatened to subpoena Mueller to testify unless his full report is made public.
"We are going to get to the bottom of this", Schiff said.
Schiff on Sunday described details the House intelligence committee has learned about Trump's efforts to secure a Trump Tower Moscow deal during the 2016 campaign as "chilling".
Barr, who oversees the investigation, has said he wants to release as much information as he can.
The Justice Department said Friday that Mueller isn't expected to submit his report on Russian interference in the 2016 election and whether Trump obstructed justice next week, quashing rumors that the probe was finally coming to an end. "I think [Attorney General William] Barr will ultimately understand that as well", Schiff explained.
Former Trump campaign chairman Paul Manafort could spend the rest of his life in prison.
In New York, the Manhattan district attorney is preparing to charge Manafort with violating state tax laws and committing other financial crimes, a move created to ensure Trump's former campaign chairman spends time in prison if the president pardons him for the convictions stemming from Mueller's probe, Bloomberg News and the New York Times reported Friday.
Mueller's prosecutors have been handing off other pending legal matters to the US attorney's office for D.C., and the Department of Justice is readying for Mueller to formally conclude his work.
But Barr indicated during his confirmation hearings that he could draft his own report to Congress and not turn Mueller's report over in its entirety. In a letter Friday, Democrats warned against withholding information on Trump on the basis of department opinions that the president can't be indicted.
Republican Senator Lindsey Graham of SC, chairman of the Senate Judiciary Committee, said regulations only require the attorney general to provide him and the panel's top Democrat a summary of what was found.
Special Counsel Robert Mueller's office said in a sentencing memo released Saturday that President Donald Trump's former campaign director Paul Manafort was a "bold" criminal who "repeatedly and brazenly" broke the law.
