On the Congressional campaign trail on Wednesday, Staten Island's district attorney took a page out of the Republican playbook—calling for the repeal of Obamacare. A month ago, however, we heard something different from Dan Donovan. NY1’s Courtney Gross filed this report.

Dan Donovan has filed his taxes, but to mark Tax Day the Congressional candidate released a tax reform plan.

“We need to reform our tax structure to make it fairer and simpler," he said.

To simplify the nation's tax code, the district attorney suggested a number of things. Among them: repealing Obamacare.

"We also need to repeal Obamacare and the taxes that came with it. Twenty or so tax increases totaling $500 billion," Donovan said.

His proposal is a sharp turn from what we heard from the district attorney just last month, though.

"One of proposals in the budget is to overturn all of Obamacare. There is good parts of Obamacare," he said on March 18. "Allowing people to keep their children on their insurance policy is a good thing until their 26 years old is a good thing. Not allowing insurance companies to reject a policy owner for a preexisting condition is a good thing."

He added, "There's parts of Obamacare that are good. There are parts that aren't good. No one is in control of all the good ideas."

We asked what changed.

"I don't think anything has changed. I have only pointed out those two things the entire time I have been running," Donovan said. "You repeal the whole thing. You take those two elements and you put them in a new health care bill."

Donovan's position on tax reform is in stark contrast with his Democratic challenger, Vincent Gentile.

Gentile, for one, wants one-time tax on profits that corporations make overseas to pay for transportation infrastructure.

"This frees up the ability of these multi-national corporations to bring these profits back to America, reinvest in America, create jobs in America and stimulate the economy," Gentile said.

"Taxing them more is going to encourage them to try to avoid paying taxes more and more. Encourage them to invest here," said Donovan.

On a more personal note, both candidates told us they would release copies of their own tax returns at a later date.
