In addition to the extra gift to corporate America Republicans slipped into the massive coronavirus bill, allowing the Federal Reserve to keep its deliberations secret, there’s also a big tax break to wealthy taxpayers that somehow got into the bill without Democrats knowing about it. Two Democrats, Rhode Island Sen. Sheldon Whitehouse and Texas Rep. Lloyd Doggett, are trying to get to the bottom of it.

“It’s really scandalous,” Whitehouse told CNN’s Manu Rafu, saying it looks like an effort “to loot the American taxpayer” in the middle of a crisis. “There’s something rotten about that—something unAmerican about that.” The New York Times reported that it did come from Senate Republicans who “inserted an easy-to-overlook provision on page 203 of the 880-page bill” to allow investors to “use losses generated by real estate to minimize their taxes on profits from things like investments in the stock market.”

Whitehouse asked Treasury Secretary Steven Mnuchin where this idea originated, and Mnuchin claimed that the “bipartisan” Senate task force came up with it. Whitehouse says he has assurances that neither House nor Senate Democrats came up with this one. He wants to know who in the White House made sure it happened.
