Advocates are urging Senate Republicans to reject a proposal to cut billions from American healthcare to extend tax breaks that primarily benefit the wealthy and corporations.

The proposal would make historic cuts to Medicaid, the public health insurance program for low-income and disabled people that covers 71 million Americans, and is the Senate version of the “big beautiful bill” act, which contains most of Donald Trump’s legislative agenda.

“With the text released earlier this week, somehow the Senate made the House’s ‘big, bad budget bill’ worse in many ways,” said Anthony Wright, the executive director of Families USA, a consumer healthcare advocacy group, in a press call.
