Senator Elizabeth Warren, the incoming chair of the Senate Banking Committee, pledged aggressive oversight of Wall Street and big technology companies on X, where she has 8.8 million followers.

"If you've been making your profits by cheating American families and scamming your investors, you better get ready for some investigations — serious ones," Warren wrote.

A Democrat from Massachusetts, Warren has spent decades advocating for stricter corporate and financial regulation. She established the Consumer Financial Protection Bureau and pushed for accountability following the 2008 financial crisis. Her past criticisms have targeted predatory lending, data privacy, and market concentration.

The Senate Banking Committee holds jurisdiction over banking, housing, securities, and federal agencies including the Federal Reserve, the Securities and Exchange Commission, and the Treasury Department. Warren will oversee confirmation of presidential nominees for key regulatory positions, including the Federal Reserve Chair and SEC Chairman.
