As the Senate Budget Committee debated the Republican tax bill on Tuesday before passing the proposal in a 12-11 vote, about a dozen people were arrested after disrupting the meeting to demand that senators reject the bill.

The demonstrators chanted, “Kill the bill, don’t kill us,” repeating the refrain that was commonly heard in protests against the Republicans’ plan to repeal the Affordable Care Act (ACA) over the summer.

Earlier this month, the Senate Finance Committee added a repeal of the ACA’s individual mandate to the bill, which the Congressional Budget Office estimated would leave 13 million Americans without health insurance. The revelation resulted in a huge push to defeat the bill by groups like Indivisible and other members of the Trump resistance, in recent weeks.

At the Dirksen Senate Office Building on Tuesday, the Capitol police arrested about a dozen protesters as the committee voted along part lines to advance the bill.

In addition to the impact the bill would have on health coverage, analyses by groups including the Tax Policy Center, the Joint Committee on Taxation, the Center for Budget and Policy Priorities, and Americans for Tax Fairness have all found that while middle class households may see tax cuts initially under the Republican plan, by 2027 most of the benefits of the proposal would be going to the wealthiest Americans.

Republicans including President Donald Trump have also insisted that average American families would benefit from the repeal of the estate tax under the plan—though the tax only applies to transfers or inheritances of wealth over $5.5 million, and actually only affects about 5,000 American families.
