Around a dozen House Republicans are uneasy about the prospect of voting for their party’s budget proposal over potential cuts to Medicaid, according to several people familiar with the conversations.

The Senate plan, passed last week, does not include Medicaid cuts. The Senate budget resolution omits tax policy but sets the spending agenda to enact Trump’s border, defense and energy policies, punting negotiations on tax policy to a later date and breaking up the spending plan into two separate measures.

President Trump cautioned House Republicans crafting a budget framework about cutting Medicaid, with some seeing a juicy target and others worried about angering voters.
