Former Trump campaign adviser George Papadopoulos has it in for former FBI Director James Comey.
House Republicans subpoenaed Comey and former AG Loretta Lynch to appear in a closed-door session.
Papadopoulos wants Comey to publicly testify about the FBI's purported mishandling of the Russia investigation.
Earlier, Papadopoulos wanted immunity to testify before the Senate Intelligence Committee.
However, on Saturday, he said he'll withdraw his request if Comey testifies publicly.
