Efforts early Tuesday to access the online marketplace in Missouri prompted a message saying traffic to the site was heavy. The website churned slowly to the log-in page.
A member of the Health Insurance Marketplace apologized for the inconvenience in a live chat with KCTV5. He said the site is "experiencing a few technical difficulties."
At midnight, Rep. Tim Huelskamp (R., Kan.) tried to sign up for the Obamacare exchanges and was met with similar issues.
"We have been warned time and time again that Obamacare is not ready for prime time," he said. "Well, it turns out that is right. When I tried to sign up for the exchanges, I was met with error messages, unfinished security forms and misspelled notices at every click."
