A number of Republicans are frustrated with the White House, fearing that voters might blame the party if the courts strike down Obamacare.
The 2010 law not only prohibited insurance companies from denying coverage for people with pre-existing health conditions, but also extended health coverage through federally subsidized individual insurance plans and an expansion of Medicaid, the joint federal and state program which offers health coverage to low-income people.
By a 5-4 vote in 2012, the U.S. Supreme Court upheld Obamacare’s requirement that people either buy a federally subsidized policy or face a tax. Congressional Republicans killed that requirement in 2017 as part of a package to dramatically reduce taxes.
Twenty Republican-leaning states filed suit, claiming without the mandate the entire law is unconstitutional. A federal judge in Texas struck down the law, but the 5th U.S. Circuit Court of Appeals will hear an appeal.
