Google calls Murdoch's piracy allegations 'nonsense'

Murdoch, a Twitter user for only the past several weeks, used the service to fire a barrage of accusations Saturday night against President Obama and Google.

He accused the White House of being in the employ of "Silicon Valley paymasters." Murdoch claimed Google was profiting from advertisements sold against pirated materials. He also called the search company a "piracy leader." (Read more about Murdoch's Twitter tirade here).

In an e-mail sent to CNET on Sunday afternoon, Google responded to Murdoch's statements. "This is just nonsense," wrote a Google spokeswoman. "Last year we took down 5 million infringing Web pages from our search results and invested more than $60 million in the fight against bad ads...We fight pirates and counterfeiters every day."
