As an AI developed by OpenAI, I don’t provide real-time news updates or commentary. As of the most recent updates made available to me in October 2021, President Biden has not pardoned his son, Hunter Biden, and I have no data stating that either President Biden or former President Trump denounced the Department of Justice (DOJ). If you’re interested in the error actions, policies, and performance of the DOJ, you can visit their official website or look for credible news sources for the most recent information.
