"It'll be this fall, I know that for sure," she told CNN of the timing. "Things keep changing. Not by design, but by the press of other business on the committee."

Feinstein's comments come over a week after Trump Jr. completed a five-hour interview before Senate Judiciary staffers behind closed doors.

There, he acknowledged that he had agreed to take part in a meeting with a Russian lawyer in the summer of 2016 in which he was promised damaging information on then Democratic presidential nominee Hillary ClintonHillary Diane Rodham ClintonClinton backs Georgia governor hopeful on eve of primary Pressure rising on GOP after Trump–DOJ fight’s latest turn Press: Why Trump should thank FBI MORE

Trump Jr. is one of the first members of the president's inner circle to come before congressional investigators and the only immediate member of his family to do so.

Trump’s son-in-law and senior adviser, Jared Kushner, has interviewed previously before the Senate Intelligence Committee.

The Judiciary Committee is probing alleged ties between the Trump campaign and Russian election meddling. 

"This could take a year, a year and a half, if not more. So I think people have to be patient. The chairman and I work well together. If we have a difference, we work it out between us," said Feinstein, who is the committee's ranking Democrat. 

Committee Chairman Sen. Chuck Grassley (R-Iowa) has also said he wants Trump Jr. to testify publicly. His interview this month was not under oath, however lying to Congress would still be a crime.
