Conservative media mogul Rupert Murdoch, whose News Corporation includes Fox News, took aim at Google and President Barack Obama on Saturday for their opposition to controversial online piracy legislation.

Obama administration officials responded on Saturday to two petitions calling for President Obama to veto the Stop Online Piracy Act (SOPA) and any similar bills, saying they would “not support legislation that reduces freedom of expression, increases cybersecurity risk, or undermines the dynamic, innovative global Internet.”

“So Obama has thrown in his lot with Silicon Valley paymasters who threaten all software creators with piracy, plain thievery,” Murdoch said in a tweet.
