They got in by a Congressional staff member - i already told you that. It doesn't matter whether they were let in or not - they were in a place they weren't supposed to be.Again, I think you're effing with me/us. I've seen your posts and I'm pretty sure you're not this stupid.
How do you think they had access to members of Congress in the first place? Do you honestly think they just showed up and started doing their interviews? Unlawful entry - as stated in the article - simply means they didn't stay with their staff guide. How was someone assigned to them if they weren't cleared to be there?
Come on man. Really think about this. Are you actually suggesting they never had permission to be there and film?
I'm way beyond explaining 'unlawful' to you.
You got caught with your pants down and now you're flailing.
