In a tweet 'Anonymous' wrote: "I've been informed a #DDoS is underway against http://www.clubforgrowth.org #Anonymous #OpWisconsin #WIunion #WeAreWI."
"#DDoS" refers to a distributed denial-of-service attack, the preferred method of attack for 'Anonymous'.
As we reported Monday, 'Anonymous' put out a statement declaring that it would target conservative groups like Americans For Prosperity and Citizens United, in solidarity with the protesters in Wisconsin. "In a world where corporate money has become the lifeblood of political influence, the labor unions are one of the few ways citizens have to fight against corporate greed. Anonymous cannot ignore the plight of the citizen-workers of Wisconsin, or the opportunity to fight for the people in America's broken political system," 'Anonymous' explained.
Ben Smith of Politico reported Monday that the AFP site was down "intermittently" on Sunday night. The Club For Growth site is back up now, though was down earlier Tuesday morning.
Club For Growth did not immediately return TPM's request for comment.
