Amy Klobuchar: Tax tech giants when they sell access to personal data

But she also has aggressively sponsored bills in the Senate to regulate the industry, by blocking mergers and making it easier for consumers to opt out of data collection, among others. She came to SXSW with another bold new idea: every time a tech giant such as Facebook or Google makes ad money, by selling access to user eyeballs, make the company pay.

"There should be some kind of a tax on it," she said. She also acknowledged the tax proposal would not be popular among industry executives. "They're going to scream when they hear this."

Elizabeth Warren: Amazon is a monopolist; limit their monopoly profits

Amazon is her Exhibit One. The popular site for shopping is increasingly becoming the maker of products. AmazonBasics offers everything from bed frames and yoga mats to jumper cables. Warren is against a single company running the marketplace and manufacturing the goods sold because, according to her, that's too much power in too few hands.

While consumers benefit from low prices, small businesses are losing. The audience broke into laughter and thunderous applause when Warren said that under her leadership, the losers would change. "The monopolist will make fewer monopoly profits. Boo hoo!"

"There is nothing laudable about endangering innocent people, and there is nothing brave about sabotaging the peaceful relations between nations," she added. Clinton emphasized that she wanted to "make it clear to the American people and to our friends and partners that we are taking aggressive steps" to hold those who leaked the documents to account.

WikiLeaks posted more than 250,000 documents online and provided them to [several newspapers] for release. The documents offer an unprecedented look at the American diplomatic process--from 1966 to cables written as recently as this past February.
