Vivek and Flynn are no less politicians than Tulsi. Of those, I would probably trust Flynn more because he spent some time in the breach (political/legal). I wish he would have fought harder against the DOJ at the beginning of his travails, but he may have thought it the best way to help Trump. Hopefully he has learned not to give a single inch.
I’ll skip General Flynn in any role as he sold out and became a foreign agent. He cannot undo that treason against the US, selling his expertise, experience, and knowledge to a foreign government.
