President Trump has never been coy about his desire to repeal and replace the Affordable Care Act. While that pledge has faced setbacks in Congress, his administration has managed to gut Obamacare by other means, like cutting financial support. The executive branch can also undermine the law in subtler ways. According to a new report, the Trump administration has been systematically wiping crucial information about the ACA from government websites over the past two years. Unlike changes to funding, these modifications often happen with little fanfare or government oversight, but they can still have a dramatic impact on Americans' access to health care resources.

The report was published Wednesday by the Sunlight Foundation, an open government group whose Web Integrity Project monitors some 30,000 government pages for updates and alterations. Looking at sites administered by the Department for Health and Human Services, it documents 26 instances in which information related to the Affordable Care Act was substantially altered or removed. Some of the changes were subtle. Others, including the disappearance of an 85-page website devoted to the ACA, were sweeping. Taken together, the researchers argue, the modifications are tantamount to government censorship and point to an increasing need for oversight of government websites.

"People rely on government information, and there’s a presumption of objectivity that comes from the [government] address," says Sarah John, director of research for the Web Integrity Project and one of the paper's coauthors. "If a website says one thing one day and a different thing the next day, what is a citizen to make of that?" HHS did not respond to a request for comment.

That the Trump administration would whittle away at these online resources may not come as a surprise; it has already effectively gutted the financial resources that the Obama administration dedicated to promoting the law. Shortly after President Trump took office, the Center for Medicare and Medicaid Services announced it would cut funding for Affordable Care Act–related outreach and advertising by 90 percent, from $100 million to $10 million. The following year, the center slashed funding even further for so-called navigators, who help people sign up for insurance.

The website changes appear to be an extension of this strategy to make it harder for the average American, and particularly the most vulnerable Americans, to find information about coverage. Among the biggest changes was the removal of an entire 85-page website listing "facts and features" about the ACA. It had included 29 fact sheets about the law, as well as a breakdown of the impact of the law in each state.

Other changes appeared to take direct aim at communities that have been disproportionately uninsured or who would be entitled to special benefits under the ACA. Some time in the weeks after President Trump's inauguration, for example, the Affordable Care Act page on the website for the Office of Minority Health was removed. Later, a page offering guidance for American Indians and Alaska Natives was also removed. The Department of Health and Human Services removed multiple pieces of content noting that women could no longer be charged more or denied coverage under the ACA, and the Office of Women's Health removed a page informing women about breast cancer screening options. Still another page on MentalHealth.gov was altered to remove text explaining that most health plans cover preventative services like depression screening and behavioral assessments for children.

In most cases, the government made these changes without any official announcement. "What’s interesting and potentially dangerous about website changes is they can be done without due process," says Rachel Bergman, director of the Web Integrity Project and another coauthor on the report. "Ultimately it can have the same consequences as a formal policy change."

Many of the modifications and removals do mirror formal policies the administration is pursuing. In August of 2018, several agencies finalized a rule to expand what are known as short-term, limited-duration insurance plans, which aren't bound by the ACA. That means that under those plans, women can be charged more for insurance, and people can be turned down for preexisting conditions. That could explain why some changes to government websites appear to downplay the rights afforded to people under the ACA. Similarly, the researchers found that some training materials for navigators had been removed, echoing the administration's broader reduction of the navigator program.
