Senate Republicans on Monday proposed steeper Medicaid cuts than those included in the House-passed version of President Donald Trump’s signature policy bill—making the bill’s passage by the July 4 deadline set by Congressional Republicans even more uncertain as Medicaid cuts have been a major sticking point for some in the GOP.

The proposal would salvage some clean-energy tax credits and phase out others more slowly, making up some of the cost by imposing deeper cuts to Medicaid than the House-passed bill would.

The Senate Finance Committee on Monday released its version of the GOP’s package that calls for enacting sweeping cuts to Medicaid and preventing a multi-trillion dollar tax hike on Americans.
