Ex-FBI boss James Comey, who was fired by Donald Trump, has agreed to testify publicly before the Senate Intelligence Committee.
Although the date of the hearing has not yet been set, it will be scheduled after the 29 May Memorial Day holiday, the committee said in a statement.
Committee chairman Senator Richard Burr said the committee wants to hear from Mr Comey on his role in the development of the US intelligence agencies' assessment that Russia interfered in last year's election.
He said he hopes Mr Comey's testimony will answer some of the questions that have arisen since Mr Comey was suddenly dismissed last week by President Trump.
