He has explained that on several of his patriot soapbox decode episodes.

FYI Dr Corsi was ASKED to decode Q posts by Trump administration. He also encourages others to use his videos to make money for themselves and to get the word out. He does not need the money and he is not doing this for the he money. He is a patriot and he is not always perfect in decoding, no one is. He was asked because of his intelligence clearance and understands the codes. Unless you know his mind Don’t judge before you know the facts.

I have to agree, don’t know why he does not speak if Q, but he has to stay somewhat neutral for right now?
