Why is Binance illegal in usa?

I'm puzzled why Binance is considered illegal in the United States. Could you please elaborate on the reasons behind this? As a leading cryptocurrency exchange platform, Binance has millions of users worldwide, including many in the US. What specific laws or regulations have been violated that led to this classification? Is it due to issues with money laundering, tax evasion, or something else entirely? Also, how does this affect US citizens who use Binance? Are they at risk of facing legal consequences? I'd appreciate it if you could provide a detailed explanation.
