for starters, the ACA was an unconstitutional governance by fiat, as Obama crafted an illegal clandestine deal with the pharmaceutical industry to get it passed. the then Secretary of Health & Human Services, Kathleen Sebelius, threatened to put insurance companies out of business if they told their clients of the impact ObamaCare would have. it illegally granted legal immunity to the Independent Payment Advisory Board from impacted patients. it broke extant federal law by conferring benefits on same-sex couples. Kathleen Sebelius rewrote SCOTUS's ruling in NFIB v. Sebelius to allow the HHS to continue coercing states into implementing ObamaCare's medicaid expansion. Obama himself illegally exempted congress and congressional staffers from ObamaCare, illegally delayed and rewrote key provisions of the ACA, and illegally exempted unions from fees levied on all other large group health-care plans.
Obama's IRS illegally issued a rule that allowed ACA subsidies and fines for plans that originated in state Exchanges, regional Exchanges, subsidiary Exchanges, or federally facilitated Exchanges; ObamaCare allows subsidies and fines only through state Exchanges. the architect of the ObamaCare farce, Jonathan Gruber, said the federal government was deliberately slow in providing a "backstop" for state health-care Exchanges: this was a calculated effort to force all states to create exchanges because citizens in states without exchanges received no tax credits but were required to pay for ObamaCare regardless.
Jonathan Gruber also said on video that the law passed thanks to the "stupidity of the American people." the white house insisted he had no official role in crafting ObamaCare but emails confirmed that to be a lie.
another Obama HHS secretary, Sylvia Matthews Burwell, illegally funded ObamaCare Section 1402 subsidy payments to insurers by shifting congressional appropriations from a different ObamaCare section. In order to fund Section 1402 reimbursements to insurers, the Obama administration illegally appropriated taxpayer dollars from GSEs (government-sponsored enterprises), the Federal National Mortgage Association (or Fannie Mae), and the Federal Home Loan Mortgage Corporation (or Freddie Mac).
