There is no basis for a court to make such a move to prevent Comey from coming before the panel to testify about President Trump's efforts to get him to pull back on the FBI's investigation of Russia's hacking the 2016 presidential race. If the testimony involved classified information, there might be a colorable argument if the former employee agreed the conversation was confidential, and both thought it was covered by executive privilege and held the conversation on that basis, but absent even that dubious argument, conversations with the president of the United States do not give him the power to revoke the First Amendment. Nor do courts engage in prior restraint , enjoining speech before it has been made.
