The question for Comey that I would like to see asked while under oath:
"Mr Comey, In your testimony to Congress, you stated that Trump never pressured the FBI to halt investigations. Later, you stated that Trump did pressure you on an investigation. Those statements are diametrically opposite and mutually exclusive. So either you perjured yourself while under oath before Congress, or you lied to the public and attempted to influence an ongoing investigation. Which of the two illegal actions did you commit?
Please feel free to consult with your lawyer prior to answering."
