Is Coinbase banned in US?

Excuse me, could you please clarify if there's any truth to the rumor that Coinbase, the popular cryptocurrency exchange platform, has been banned in the United States? I've heard conflicting reports and would like to get a definitive answer from an expert in the field. It would be greatly appreciated if you could provide me with some insight into the current status of Coinbase's operations in the US and any potential legal challenges or restrictions it may be facing. Thank you in advance for your assistance.
