Is doxxing legal in the US?

I'm curious to know, what is the legal status of doxxing in the United States? Is it considered a criminal offense or does it fall under a different category of law? Can individuals be held liable for revealing personal information of others online without their consent? How does the law differentiate between doxxing and other forms of online harassment or defamation? And, what are the potential consequences for those who engage in doxxing practices?
