HAMPTON, Va. (WVEC) -- Since Donald Trump won the election, the federal government has seen a record increase in the number of people enrolling in Obamacare, which the president-elect has promised to repeal.

On November 9, the day after the election, an unprecedented 100,000 people signed up at Healthcare.gov, according a tweet sent by Health and Human Services Secretary Sylvia Burwell.

Trump said he would repeal Obamacare within his first 100 days in office.

David Williams, a self-employed carpenter in Hampton, said his family is covered through Obamacare. Williams, who is diabetic, said he is concerned about Trump's plan to repeal the service.

"I just don't know whether pre-existing conditions are covered, what it would cost," Williams said. "It's just a lot of change and stuff to go through in less than 48 hours."

Gary Byler, who helped Trump's campaign in Hampton Roads, said people enrolled in Obamacare should not be worried about possible changes.

"The folks who have Obamacare right now, absolutely do not panic. Nobody is looking to be throwing people out of programs, quite the opposite," said Byler. "We're looking to enroll more folks on free market systems. And it will be more affordable."
