Barry Lynn, who was in charge of the Open Markets division, was asked to leave the organisation by the chief executive of the think-tank, Anne-Marie Slaughter, according to a report in The New York Times.
The report said the Foundation, set up in 1999, had received more than US$21 million from Google, Alphabet chairman Eric Schmidt and his family's foundation.
Lynn told the NYT that soon after he had posted a statement praising the EU move against Google, Schmidt made his displeasure known to Slaughter.
Let me be clearer in era of fake news; facts are largely right, but quotes are taken way out of context and interpretation is wrong. https://t.co/ynlNR8FDEx— Anne-Marie Slaughter (@SlaughterAM) August 30, 2017
But a few days later, the report said, Slaughter called Lynn to her office after telling him via email, "the time has come for Open Markets and New America to part ways".
While Slaughter told Lynn that the decision was not based on his work, she accused him of "imperilling the institution as a whole".
Lynn said: “Google is very aggressive in throwing its money around Washington and Brussels, and then pulling the strings. People are so afraid of Google now.”
A Google spokesperson Riva Sciuto told the paper: "We don’t agree with every group 100 percent of the time, and while we sometimes respectfully disagree, we respect each group’s independence, personnel decisions and policy perspectives."
New America’s executive vice-president Tyra Mariani and Sciuto said Google was continuing to pour money into the Foundation.
After the NYT article was put online, Slaughter claimed in a tweet that it was false. But she did not cite any errors either in the tweet, or in a statement issued to the newspaper.
