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.

Senate Republicans are proposing deeper Medicaid cuts, including new work requirements for parents of teens, as a way to offset the costs of making President Donald Trump’s tax breaks more permanent.

The legislation keeps some House provisions, like new Medicaid rules, while making significant changes in other areas, including Medicare and the state and local tax deduction.
