Social media queen Rep. Alexandria Ocasio-Cortez (D-N.Y.) used her Twitter platform to defend journalists amid a series of sweeping layoffs across the media industry.

In a Saturday tweet, the freshman congresswoman cautioned that “the biggest threats to journalism right now are tech monopolies & concentration of ownership,” advocating for “high-quality journalism.”

Without a diversity of news outlets, she warned, “our democracy will continue to crumble.”
