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.

Republican leaders are aiming for quick negotiations over needed changes to the newly unveiled Senate tax bill which lacks the votes to secure majorities in both chambers as written.

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.
