BOSTON (AP) — State campaign finance officials have required a group that funneled large donations to 2016 ballot questions regarding charter schools and marijuana legalization to disclose the identity of its donors.

Officials said Tuesday that the Massachusetts-based Strong Economy for Growth raised and spent almost $1.2 million to support the ballot questions. The bulk of the money, $990,000, went to Great Schools Massachusetts, a committee set up to support a ballot question about lifting state caps on charter schools, but the question failed.

Strong Economy for Growth also funneled $178,000 to The Campaign for a Safe and Healthy Massachusetts, a group opposed to a question about legalizing the recreational use of marijuana. That question was approved by voters.

The biggest donation to Strong Economy for Growth, $600,000, came from a nonprofit, QXZ Inc., whose major donor is Jeffrey Yass, a charter school advocate, according to campaign finance officials.
