Self-described socialist Alexandria Ocasio-Cortez announced on Twitter late Tuesday that she will join California Democratic Rep. Maxine Waters on the influential House Financial Services Committee, which oversees Wall Street and the housing industry. California Rep. Katie Porter, Michigan's Rashida Tlaib, Hawaii Rep. Tulsi Gabbard, and Massachusetts Rep. Ayanna Pressley have also reportedly been tapped for the committee by Democratic House leaders, and a vote finalizing their appointments is expected within days.
