Schiff has introduced the 'whistleblower' into the record. Should be easily able to call that person to testify based on that.
Well he started talking about the whistleblower, referring to him as "the whistleblower". Would seem to be putting him/her directly into the record. Did not name the person.
Someone the other day said he was protected while in the House, but not in the Senate. I don't think he can knowingly present false evidence.
Yes, Yovanovitch is finished.
