Bernie Sanders: Hillary Clinton's Fundraising Is 'Obscene'

Democratic presidential hopeful Sen. Bernie Sanders (I-Vt.) on Sunday criticized rival Hillary Clinton's ties to deep-pocketed donors on Wall Street and in the pharmaceutical industry.

"It is obscene that Secretary Clinton keeps going to big-money people to fund her campaign," Sanders said in an interview on CNN 's "State of the Union."

The senator added that Clinton "has now raised well over $15 million from Wall Street for her super PAC, and millions more from the fossil fuel industry, and from the drug companies."

The former secretary of state is scheduled to hold a campaign event next month  in San Francisco. Clinton is asking for $353,400 for two seats at a table with herself, actor George Clooney and his wife, Amal Clooney.

While Clinton has courted big donors in the Democratic Party , Sanders has done particularly well with small donors. Almost all of the $75 million  his campaign raised last year, for example, came from small donors.
