Cotton said the CAT would collect vast amounts of private information of every American investor, including any American with a retirement account, without any suggestion of wrongdoing by the investor. Because Congress never authorized or provided funding for the CAT, the SEC’s proposed scheme would force the investors themselves to pay to be surveilled, increasing their costs, and invading their privacy all at once.

 “The SEC never brought this proposal before Congress to request funds because the Biden administration knows the program is a gross overreach that would suck up the personal data of millions of law-abiding Americans. More than that, the SEC has shown it is incapable of safely storing sensitive data. This program needs to be killed before it begins,” said Senator Cotton.
