I think 200+ agents were more than a handful. And considering there's actual documentation that they were there, I'd believe it. Though, I suppose I'm not surprised a leftist doesn't believe Trump, I've seen actual "journalists" rather believe known liars like China over the guy.
Look, point is, non-citizens simply don't have the same rights as actual citizens. And considering the mess Biden left behind, drastic measures need to be taken. And even on the rare case an actual citizen gets caught up in the net, all that needs to be done is go through the database to see if they're a citizen, tourist, or illegal. If they're fine, they're let go. If they're not, they'll be sent home (or into a prison of their home nation in case of the violent criminals).
Besides, where was this "depriving constitutional rights" attitude when every single non-FBI Jan 6er got the book thrown at them and got, in the vast majority of cases, thrown into prison without trial? You can't blame a guy for punching you in the face when you punched them first, can you?
