Yes, but Biden could be brought up on charges here for using his office to coerce another country for personal gain. I believe that the ICIG is limited to oversight of just the IC, not anywhere else in the executive branch. The Rose Law Firm lawyer who is representing the so called whistleblower is deeply involved in whistleblower issues and the IC. I wouldn't be surprised if he auditioned whistleblowers to keep the Left's opposition to Trump alive.
