Alexandria Ocasio-Cortez said she wants Wall Street to tell Congress why it’s lending to private prisons that hold undocumented immigrants. "We’re going to hold oversight hearings to make these banks accountable for investing in and making money off of the detention of immigrants," she said at an event last week in Queens hosted by the nonprofit Make the Road New York. "Because it’s wrong.”... JPMorgan Chase & Co. and Bank of America Corp., the two biggest U.S. banks, are among lenders to GEO Group Inc. and CoreCivic Inc., which run facilities that have held immigrant families.
