The records, gleaned from White House visitor logs reviewed by NBC News, show that senior White House officials had a dozen meetings in 2009 with three health-care advisers and experts who helped shape the health care reform law signed by Romney in 2006, when the Republican presidential candidate was governor of Massachusetts. One of those meetings, on July 20, 2009, was in the Oval Office and presided over by President Barack Obama, the records show.

“The White House wanted to lean a lot on what we’d done in Massachusetts,” said Jon Gruber, an MIT economist who advised the Romney administration on health care and who attended five meetings at the Obama White House in 2009, including the meeting with the president. “They really wanted to know how we can take that same approach we used in Massachusetts and turn that into a national model.”
