"It calls into question whether the people who initiated and passed this legislation had any clue about what they were doing," he said late Tuesday.
Roberts, who heard the news from a Daily Mail reporter who called seeking comment, said more time would certainly help businesses in the state. He said he hears frequently from concerned business owners who have questions about the law's requirements.
Typically, he said business owners want to know what type of coverage they will have to provide, when they have to provide it, to whom they must provide it and where are they supposed to receive it. Apart from who is eligible for coverage, Roberts said there have been few answers from the federal government.
He was skeptical of reports that the health care exchanges created by the legislation wouldn't be affected.
"I'm not suggesting it was delayed out of mercy, it was delayed out of necessity," Roberts said.
West Virginia Attorney General Patrick Morrisey was also quick to point to the delay as evidence of problems with the entire legislation.
The Republican who won office in 2012 is an outspoken critic of the Affordable Care Act. He voiced more of those concerns Tuesday evening on Twitter.
"Employer mandate one section of a flawed law with a negative impact on (West Virginia)," Morrisey tweeted. "This is the first of more 'shoes to drop' before enrollment begins."
Morrisey also tweeted that Tuesday's decision could show Obama's administration "is understanding just how flawed and delayed its implementation rollout has been."
Rep. David McKinley, R-W.Va., was the only member of the state's delegation to voice his opinion on Twitter Tuesday evening. He said the delay was more evidence of the "Obamacare train wreck."
Charleston car dealer Joe Holland recently filed a lawsuit over the legislation. He wants a judge to block a mandate that he provide insurance to his employees that covers abortion and contraceptives.
Holland, who describes himself as a born-again Christian, claims that mandate violates his religious beliefs. He says he provides health insurance to about 150 employees already, but that abortion and contraceptives aren't covered by the plans he offers.
Obama's administration pushed for the rule as a way to expand coverage and ease the costs of birth control, which can average about $600 a year.
Jeremiah Dys is an attorney and head of the Family Policy Council of West Virginia, a conservative Christian advocacy organization. He is also part of the legal team representing Holland.
Reached late Tuesday, Dys said he wanted to learn more about the delay before commenting on how it might affect Holland's lawsuit.
