One in five Obamacare customers in 2014 were small business owners or self-employed, according to an Obama administration report seeking to highlight the impact of repealing the law.

The Treasury Department issued a report Thursday that showed about 1.4 million Obamacare customers were a small business owner or self-employed in 2014. That was the first year Obamacare’s marketplaces went online; when 8 million signed up for plans despite the botched rollout of healthcare.gov.
