nah, it’s not legal. It’s just not illegal, yet. And it matters the time, place and reason for which they lie.
See post 9. It’s got nothing to do with 1A issues. If it was, then there’d be no such thing as perjury.
It is legal for them to lie in Congress. They have congressional immunity...look it up. Look at the Jan 6th hearings and pretty much any congressional hearing. Nothing but lies and they can and do get away with it.
