“As one of my Republican colleagues said in a moment of honesty, if they don’t pass this tax giveaway bill, financial contributions will stop. And a Republican House member said big donors told him to pass the tax bill — or don’t ever call them again,” Warren said. “Let's call this out for what it is — it’s government for sale.”

“And that’s how you end up with a $1.5 trillion tax giveaway to corporations at a time of record corporate profit.”

Warren’s comments come on the heel of a joint op-ed she wrote with Sen. Bernie Sanders Bernie SandersOutrage erupts over Breonna Taylor grand jury ruling Dimon: Wealth tax 'almost impossible to do' Grand jury charges no officers in Breonna Taylor death MORE (I-Vt.) in which they criticized Republicans for pushing an agenda they say is "widely disliked by the American people."

“Despite a booming stock market and record corporate profits, workers in this country are being squeezed by flat wages, soaring household expenses and declining savings,” Warren and Sanders write. “They want Washington to start working for them and to spend tax dollars investing in our future — not bankrupting it.”

“Congressional Republicans face a choice,” they continue. “Will they spend this week just trying to deliver partisan tax breaks for the rich? Or will they work with Democrats to pass a budget that supports working people?”

House Republicans passed the final version of the GOP tax bill on Tuesday, and the Senate is expected to follow suit later Tuesday evening.

The bill lowers the top individual tax rate from 39.6 percent to 37 percent and slashes the corporate tax rate from 35 percent to 21 percent.

It also increases the exemption amounts for the individual alternative minimum tax and the estate tax, and eliminates the ObamaCare individual mandate.

The House will have to revote on the bill Wednesday after the Senate parliamentarian ruled that three provisions in the bill violated Senate rules.
