This is a grassroots organization doing this and in fact its funding and support mostly comes from Americans, such as casino magnate Sheldon Adelson and the Israeli-American Council.
James Bamford has written at least 3 good articles about Israeli government influence of US civil society (social media) and elections (the leak of the DNC hack materials), all in the last year or so, at The Nation: https://www.thenation.com/authors/james-bamford/
