(CNN) With the 10-year anniversary of the Affordable Care Act fast approaching, former President Barack Obama highlighted the landmark health reform law's benefits in a new video released Tuesday.

"With your help, it's the closest we've ever come to universal coverage in America," Obama said in the 90-second clip released by Protect Our Care, a liberal advocacy group. "There are people alive today because of what you did. There are 135 million Americans whose pre-existing conditions are now protected because of what you did."

He added, "That's something worth celebrating, but it's also progress worth protecting."

Obama filmed several videos promoting the ACA -- usually with a humorous bent -- while he was in office and then more recently at annual open enrollment time for the Obamacare exchanges. The appearances have been aimed at reminding consumers of the deadline to sign up for coverage at a time when the Trump administration has slashed funding for marketing and outreach.

But Tuesday's video was serious, emphasizing that voters protected Obamacare in the 2018 midterm elections, when Democrats took control of the House of Representatives, effectively ending President Donald Trump and GOP lawmakers' quest to repeal the law through congressional action for the time being.
