AUSTIN, Texas - The Texas Attorney General's office has opened an investigation into LinkedIn over allegations that the professional networking platform misleads consumers with advertising and profiting from misleading or fake job listings, otherwise known as "ghost jobs." What we know: Texas announced on Tuesday it has issued a Civil Investigative Demand (CID) seeking documents, data and internal communications related to LinkedIn's advertising, marketing, job listing verification practices and its Premium subscription services.

The investigation centers on whether LinkedIn violated Texas' consumer protection laws by promoting paid subscription services while allegedly failing to disclose that some job listings on the platform may not actually be representative of hiring opportunities.

Dig deeper: LinkedIn is owned by Microsoft and the world's largest professional networking platform, with more than 1 billion registered users worldwide.
