Delayed energy projects and regulatory hurdles to domestic oil production not only cost the United States economy billions of dollars and millions of jobs, but they also stand in the way of an elusive goal: true American energy security.

Our Keystone legislation received strong bipartisan support in the Senate. Although it didn't receive the 60 votes necessary for passage, 56 senators - a majority - voted in favor of the bill. Despite President Obama's actively lobbying against the bill, we still won the support of 11 Democrats.

You don't get an economy growing by raising taxes.

The key to revenue growth is tax reform that closes loopholes and that is pro-growth. Then with a growing economy, that's where your revenue growth comes in, not from higher taxes.

Education is critical not only to each one of us individually, but also to build the economic vitality of our state.

The Keystone XL project has built strong safety measures into its design with the newest technology. Additionally, 80 percent of the new Canadian oil sands are being developed 'in situ,' meaning, it has a similar carbon footprint and emissions as conventional oil wells.

Caring for our seniors is perhaps the greatest responsibility we have. Those who walked before us have given so much and made possible the life we all enjoy.

Democrats with a good understanding of the need for strong energy policy in our country, especially in these difficult economic times, recognized the importance of the Keystone XL pipeline.

If you take a look at Medicare, there are things we could do, not just tort reform but truly reform the whole reimbursement system which will help in terms of reducing costs and creating the right kind of incentives for savings.

Nowadays, business is all about productivity - and our folks produce.

On Earth Day, we celebrate all the gifts the world and nature make available to us. We recognize our complete dependence on its bounty. And we acknowledge the need for good stewardship to preserve its fruits for future generations.

If we're going to create the best business climate to create higher paying jobs and retain our young people, we're going to have to build a workforce prepared for the opportunities of the future.

One of the key things that we did at Bank of North Dakota that I worked to try to do with our state economic development is make sure we are customer-service oriented.

Since 2006, we have surpassed Alaska, Oklahoma, Louisiana, and California in oil production to become the second largest oil-producing state in the nation, trailing only Texas. In 2012, North Dakota produced more than 245 million barrels of oil and provided nearly 11 percent of all U.S. output.

Our single greatest challenge is the ability to move power to markets outside North Dakota.

The reality is that nearly 80 percent of the world's purchasing power lies outside the United States, and if we don't tap those markets, others will.

The irony of environmental opposition to the Keystone XL project is that stopping the pipeline to the U.S. will not stop production in the oil sands of Canada. Instead of coming to the United States, the oil will still be produced and shipped by rail or a pipeline similar to the Keystone XL to Canada's Pacific Coast.
