In my time in the U.S. Senate, I tried to craft an energy policy... I will be part of President Obama's efforts to achieve energy independence and enhance the landscape. I am also part of his reform agenda.

Our country has suffered from an on-again, off-again energy policy that has failed to get us to energy independence. As President Obama has said, we need a comprehensive energy plan for the country that includes conventional resources like oil and gas, but that also takes advantage of wind, solar, biomass, geothermal, and other renewable resources.

Dr. Martin Luther King Jr. is one of my personal heroes.

Frankly that's what makes such a big difference between President Obama on one hand and Mitt Romney on the other. Gov.

The way Americans most understand the history of Latinos in this country, a lot of it is being told now through the lens of what's happening with the immigration debate. While that's an important debate that has security and moral implications, in my view, there's also a huge history of Latinos in the United States that's never been told.

Shale gas has provided the United States the opportunity to have 100 years of supply that is domestically produced. If we are going to develop natural gas from shale, it has to be done in a safe and responsible manner.
