Is Pence Trying to Invoke Executive Privilege?

The executive privilege claim here would come back to the Supreme Court precedent from the 70s with Nixon. That is still his right and his standing to invoke it, but it will likely fail in a be far weaker legal case than what Pence is apparently considering doing. And that's probably why Pence isn't really going with that line of argument. If I need to get the throw away, the legislative activity one is a far more interesting one, far more legally confusing one, which is a late thing longer.
