Billionaire Tom Steyer threw his support behind a four part advertising campaign that intends to convince its viewers that the Keystone XL pipeline would hurt the economy and the communities around it. The USD1 million campaign aims to block the construction of the pipeline.

Steyer appears on the first advertisement and he said, "Foreign countries will get more access to more oil to make more products to sell back to us, undercutting our ecconomy. Here's the truth: Keystone oil will travel through America not to America."

The founder of hedge fund Farallon Capital Management LLC would air the commercial two months after the American Petroleum Institute stated on television and online advertising that the Keystone project 'is a boon to job growth in the US."

In a newspaper advertisement by the oil industry lobby group, "Rarely do leading Republicans, Democrats, business leaders and labor unions all agree. But on Keystone XL, they do." 

The Keystone facility would carry 830,000 barrels a day from Alberta, Canada's oil sands as well as other oil shale locations in the US to refineries located on the coast of the Gulf of Mexico.
