They may also suspect, or figure out, that the government’s investigation has been triggered by a whistleblower-led lawsuit and may be able to deduce who the whistleblower is. But until the seal is lifted, the government will not disclose the identity of the whistleblower, and neither may the whistleblower or his or her lawyers.
