The private interview with President Donald Trump's son will be on December 6, they said. They were not authorised to speak publicly and spoke only on condition of anonymity.
The Senate intelligence committee also hopes to interview Trump Jr. before the end of the year, according to a spokeswoman for the committee's chairman, Republican Senator Richard Burr.
Both committees have been investigating a meeting that Trump Jr. and other Trump campaign officials held with Russians in 2016. They are also interested in messages he exchanged during the campaign with WikiLeaks, the website that leaked emails from top Democratic officials during the campaign.
