When politicians fail to live up to their promises, they rarely have to pay a price. But Jonathan Gruber is paying the price for President Obama’s failure to fulfill his promises for the Affordable Care Act, as the latest issue of Bloomberg Businessweek reports.

Rich Weinstein is not a reporter. He does not have a blog. Until this week, the fortysomething’s five-year old Twitter account had a follower count in the low double digits.

“I’m an investment adviser,” Weinstein tells me from his home near Philadelphia. “I’m a nobody. I’m the guy who lives in his mom’s basement wearing a tinfoil hat.” (He’s joking about the mom and the tinfoil.)

He’s also behind a series of scoops that could convince the Supreme Court to dismantle part of the Affordable Care Act. Weinstein has absorbed hours upon hours of interviews with Jonathan Gruber, an MIT professor who advised the Massachusetts legislature when it created “Romneycare” and the Congress when it created “Obamacare.” Conservatives had been looking for ways to demonstrate that the wording of the ACA denied insurance subsidies to consumers in states that did not create their own health exchanges. Weinstein found a clip of Gruber suggesting that states that did not create health insurance exchanges risked giving up the ACA’s subsidies; it went straight into the King v. Burwell brief, and into a case that’s currently headed to the Supreme Court.

Why did Weinstein search for clips about Gruber?

Weinstein dates his accidental citizen journalism back to the end of 2013 and the first run of insurance cancellations or policy changes. He was among the people who got a letter informing him that his old policy did not meet ACA standards.

“When Obama said ‘If you like your plan, you can keep your plan, period’—frankly, I believed him,” says Weinstein. “He very often speaks with qualifiers. When he said ‘period,’ there were no qualifiers. You can understand that when I lost my own plan, and the replacement cost twice as much, I wasn’t happy. So I’m watching the news, and at that time I was thinking: Hey, the administration was not telling people the truth, and the media was doing nothing!”

So Weinstein, new plan in hand, started watching the news. “These people were showing up on the shows, calling themselves architects of the law,” he recalls. “I saw David Cutler, Zeke Emanuel, Jonathan Gruber, people like that. I wondered if these guys had some type of paper trail. So I looked into what Dr. Cutler had said and written, and it was generally all about cost control. After I finished with Cutler, I went to Dr. Gruber. I assume I went through every video, every radio interview, every podcast. Every everything.”
