What you need to know on Wall Street today

Welcome to Finance Insider, Business Insider's summary of the top stories of the past 24 hours.

US lawmakers are considering a bill to overhaul financial regulation in the US and unravel several post-financial crisis measures. The House Financial Services Committee is holding hearings Tuesday on the Financial CHOICE Act, a more than 589-page bill that introduced by Republican Congressman Jeb Hensarling.

In a break with tradition, Democrats requested time for opening statements. Democrat Maxine Waters opened:

It's an invitation to another Great Recession or worse." You can stay up to date with the latest from the hearing here.
