Speaking Wednesday afternoon from Boston’s historic Faneuil Hall, President Barack Obama will deliver a speech on his landmark Affordable Care Act, known colloquially as Obamacare, at 4 p.m. ET. The address will center upon “the importance of providing all Americans with quality, affordable health insurance” and its relation with the healthcare law of Massachusetts, which then-Governor Mitt Romney signed into law in the very same hallowed halls of Faneuil.

The milestone measure of the president’s administration, Obamacare has been a controversial topic since it passed the Harvard Law School graduate’s desk and even more so as of late due to its direct tie with the government shutdown. Healthcare.gov, the hub of Obamacare, has subsequently rolled out with a slew of glitches and other major problems that inadvertently prohibit site-goers from purchasing healthcare options via the site. On Tuesday, Marilyn Tavenner, administrator for the Centers for Medicare & Medicaid Services, spoke in front of the House Ways and Means Committee to apologize on the administration’s behalf.

“To the millions who have tried to use HealthCare.gov, we want to apologize to you,” she said. “This initial experience has not lived up to our expectations, or the expectations of the American people, and it is not acceptable.”

Romney, for his part, weighed in on the Affordable Care Act via Facebook Wednesday morning:

In the years since the Massachusetts health care law went into effect nothing has changed my view that a plan crafted to fit the unique circumstances of a single state should not be grafted onto the entire country. Beyond that, had President Obama actually learned the lessons of Massachusetts health care, millions of Americans would not lose the insurance they were promised they could keep, millions more would not see their premiums skyrocket, and the installation of the program would not have been a frustrating embarrassment. Health reform is best crafted by states with bipartisan support and input from its employers, as we did, without raising taxes, and by carefully phasing it in to avoid the type of disruptions we are seeing nationally.

It’s unclear at this point whether President Obama will address the website’s specific issues during Wednesday’s much-anticipated speech, but the historical significance of the venue, at least, is certainly not lost on anyone.
