In the final week before voters decide on Amendment 66, the campaign supporting the education tax increase received $2 million in donations from Melinda Gates and a charity run by New York Mayor Michael R. Bloomberg.
The donations drew criticism from conservatives opposed to the tax increase.
Mr. Bloomberg’s donation came from the Bloomberg Philanthropies. The Gates check came from Melinda Gates personally, not the Bill & Melinda Gates Foundation.
The tax increase would generate $950 million, all of which would be directed to local school districts.
