President Donald Trump's eldest son and a former business associate of the president are due to testify to the U.S. House of Representatives Intelligence Committee this week, as it continues its investigation of possible Russian involvement in the 2016 election, a source familiar with the schedule said.

Donald Trump Jr. is due to appear before the committee on Wednesday and Felix Sater, a Russian-American who was a former Trump business associate who claimed deep ties to Moscow, on Thursday, the source said. Neither session will be public.
