I think the counts for lying under oath will be numerous. Plus I think Mueller will throw the book at him on the omissions when applying for a security clearance (and there could be multiple charges in that regard). And the coup de grace will likely be the conspiracy charges. I think there will an obstruction charge and a conspiracy to obstruct. The distinction between the obstruction and conspiracy to obstruct is important (the latter signalling the involvement of others). There could be multiple obstruction charges (one relating to instructing Flynn to lie, others related to the subsequent investigation). Finally, to the extent there is a charge regarding quid pro quo with the Russians, it is likely to be in the form a conspiracy to engage such an arrangement.
