Official government websites are starting to display messages on their homepage blaming Democrats for the government shutdown.

“Due to the Democrat-led shutdown, website updates will be limited until full operations resume,” the State Department’s website reads.

Disagreements over funding stem from a deadlock in Congress over Democratic demands over health care – and Republican efforts to kick that can down the road.

At issue are tax credits that have made health insurance through the Affordable Care Act more affordable for millions of people since the COVID-19 pandemic. The credits are set to expire at the end of the year if Congress doesn’t extend them – which would more than double what subsidized enrollees currently pay for health insurance premiums, according to a KFF analysis.

Federal department websites have adopted divergent – and at times partisan – strategies in public messaging on the government shutdown.

“The Radical Left in Congress shut down the government. HUD will use available resources to help Americans in need,” reads a message greeting visitors to the official website of the Department of Housing and Urban Development.

“Due to the Radical Left Democrat shutdown, this government website will not be updated during the funding lapse. President Trump has made it clear he wants to keep the government open and support those who feed, fuel, and clothe the American people,” reads another message on the Agriculture Department’s official website.

“Democrats have shut down the government,” reads a pop up message at the top of the Justice Department’s website.

Websites for the Commerce, State and Transportation Departments included notices that webpages may experience delayed updates due to “a lapse in appropriations” but did not include references ascribing partisan blame.

Agencies including the Treasury and Health and Human Services Departments did not immediately display any references to the shutdown.
