Obamacare under scrutiny this week, (Creative Commons/Shan213)

Three weeks after its launch, national health coverage is still a struggle for millions of Americans. 

A combination of high demand and confusion among various healthcare contractors has caused serious issues for many people using HealthCare.gov. 

House Speaker John Boehner is only too eager to point out that "We've got the whole threat of Obamacare continuing to hang over our economy like a wet blanket."

The president, however, is trying to honestly and effectively address the many issues that loom within the newly implemented healthcare system. 

In response to the tumultuous implementation, on Wednesday White House officials told NBC News that they plan to soften the deadline for when Americans must purchase health insurance, pushing back the date by as much as six weeks. 

The current law requires citizens to sign up for insurance by March 31 to avoid fines, but the new change would only require that people begin enrollment by then. 

According to Kathleen Sebelius, the federal Health and Human Services Secretary, the President did not know of the problems with the healthcare website before its launch. 

As the head of the deferral government responsible for the irksome rollout of the health insurance marketplace, many Republican are calling for her resignation. Sebelius, however, continues to remain silent about whether or not she will indeed stop down. 

“I think my job is to get this fully implemented and to get the website working right,” Sebelius told CNN. “And that's really what I'm focused on.

Cheryl Campbell, senior vice president of CGI Federal, however, seems to think that the kinks in the launch of the online health insurance marketplace were unavoidable. 

While the fact that her company was paid millions to create the healthcare website may alter her views, Campbell says that “no amount of testing” could have prevented the troublesome launch of the website. 

Campbell plans to elaborate on this important issue in the testimony that she has prepared to deliver to the House on Thursday. 

“this complex with so many concurrent users, it is not unusual to discover problems that need to be addressed once the software goes into a live production environment,” argues Campbell. 

With much of President Obama’s legacy riding on the fate of nationalized healthcare, Thursday’s hearing may have far-reaching consequences for the president’s administration.
