Yes, Kavanaugh is a shameless liar. But he should always be called what's more pertinent: a perjurer

You don’t have to look far to find a list of Judge Brett Kavanaugh’s lying under oath these days. There’s a legal penalty for persons convicted of that. But it hardly ever gets imposed. Indeed, people violating their oath to tell the truth are rarely even called out for it, much less charged or convicted. I am not a lawyer. But it seems to me this ought not to be the case. And surely no perjurer should ever be allowed to sit on the federal court bench in any capacity.

Here’s the Congressional Research Service scrutinizing the relevant statutes in a 24-page white paper:

Lying, or making a false statement, is a federal crime under a number of circumstances. It is afederal crime to make a material false statement in a matter within the jurisdiction of a federal agency or department. Perjury is also a federal crime. Perjury is a false statement made under oath before a federal tribunal or official.  Moreover, some false certifications are punishable as perjury by operation of a federal statute. Subornation of perjury is inducing someone else to commit perjury. It, too, is a federal crime if the perjury induced is a federal crime. Finally, conspiracy to commit any these underlying crimes is also a separate federal crime.5 Moreover, a defendant under investigation or on trial for some other federal offense may find upon conviction his sentence for the underlying offense enhanced as a consequence of a false statement he made during the course of the investigation or trial. This is an overview of federal law relating to the principal false statement and to the three primary perjury statutes.
