Maybe DHS could meet with Wheeler after they arrest him and detain him in Gitmo for insurrection, sedition and fomenting riots? I’m sure they would have plenty of time to chat then.
If I were advising DHS, they would only meet with Wheeler after he gave a written authorization to access all his personal and official email and other electronic communication accounts as well as all social media accounts, complete with passwords. If he is not aiding and abetting insurrection and other violations of federal law, what does he have to hide?
