Steven Tepp is a lawyer with the U.S. Chamber of Commerce. He says piracy of books, music, movies and other forms of intellectual property hurt the economy and threaten jobs.

STEVEN TEPP: "These rogue sites are hurting American jobs, stealing American jobs, they're harming American consumers and they have no business being on the Internet."

But many online businesses like blogs, news sites and search engines say the laws force them to become censors.

David Smith is with the Potomac Institute for Policy Studies. He says the proposed laws would hurt Wikipedia and other sites that depend on material provided by people who use the sites. He says websites would be required to police all the material they carry.

DAVID SMITH: "It creates a legal situation in which a complainant can go before a judge and get an order, and it then makes the various Internet companies, the Internet service providers, responsible for what they're carrying. And, this is where the rub (problem) comes, because it basically turns the Internet service provider into a monitor."

The House and Senate are expected to work on the bills in the coming weeks. But after the online protests, some lawmakers have already said they have doubts about the bill. Republican Senator Marco Rubio urged lawmakers to take more time to consider the concerns of both supporters and opponents of the bills.

Obama administration spokesman John Carney said the president opposes any law that hurts freedom of expression or security.
