billion restructuring of MassHealth. In December 2016, Baker announced his support for the 21st Century Cures Act passed by the 114th U.S. Congress. In January 2017, in an open letter to U.S. House Majority Leader Kevin McCarthy, Baker defended certain provisions of the ACA and urged the 115th U.S. Congress not to repeal the law too quickly and disrupt insurance markets.
