Shapiro is not a conservative.
He apparently is infected with a strong case of TDS.
Mueller should already have 80% of whatever evidence is out there. Shapiro should know what that evidence is by now.
You are absolutely right. Shapiro is a young George Will: a pretentious self promoter, a glib pseudo conservative, a pseudo intellectual. His job (assigned by his corporatist, globalist paymasters) is to corral as many millennials as possible into a fake conservative herd which is friendly toward globalism, corporatism, and statism.
