Ravitch rallies teachers vs. ‘astroturf’

Politico:

Ravitch’s public speaking schedule over the last year included more than a dozen speeches across the country to local AFT and NEA affiliates. Brill suggested that some of those appearances carried a price tag of between $15,000 and $20,000. But Ravitch, for her part, said she has never received speaking fees approaching the sums that Brill claims.
“That is a flat out untruth,” Ravitch told POLITICO. “Most of my speaking appearances to union groups have been for free.”
“Most of the time that I speak to unions it has been for free.”
Spokesmen for NEA, AFT and the Gates Foundation all declined to comment for this story.
