California's Consumer Privacy Act (CCPA) is set to take effect on January 1, granting state consumers the right to know what information companies have on them, the right to have that information deleted, and the right to opt-out of the sale of that information. The law has sparked concern among tech companies in Silicon Valley, who have lobbied to weaken its provisions. Some companies are now pushing for a federal privacy bill that would override the CCPA. The law is similar to Europe's GDPR, which has already led to significant fines for non-compliant companies.
