The people of Colorado elected Mark Udall to the U.S. Senate in 2008. Prior to that, he represented the state’s 2nd Congressional District for five terms (from 1999-08). He also served one term in the Colorado State Legislature as a member of the General Assembly (1997-99), representing the 13th District, which encompassed the community of Longmont and parts of southern Boulder County.
In the U.S. Senate, Mark serves on four committees: Armed Services, Energy and Natural Resources, the Select Committee on Intelligence and the Special Committee on Aging. Reinforcing his priority of protecting our Western lands, Mark chairs the National Parks Subcommittee of the Energy and Natural Resources Committee. Mark’s committee assignments give him a platform to address many issues important to Colorado, including national security, energy, the economy, clean energy jobs, and natural resources.
Mark is known for reaching across party lines to solve problems and for his willingness to work with people, including those with whom he has philosophical differences. In 2011, he drew national attention for calling on his colleagues to bridge the partisan divide by sitting together – rather than separated by party – at the President’s State of the Union address. Mark’s inclusive and bipartisan approach has also led to a number of legislative achievements, including bills to reduce wildfire risk and bark-beetle infestation; and legislation promoting the development of Colorado's aerospace industry, and the clean energy and high technology sectors. Mark led efforts to successfully create the James Peak Wilderness and to pass legislation transforming the Rocky Flats Nuclear Weapons facility into a wildlife refuge. He's also championed health care for workers and retirees from the nation's nuclear weapons complex and consumer protections against abusive and predatory credit card companies.
Mark doesn't shy away from making difficult decisions in order to put our country’s fiscal house in order. He is an active proponent of smart budgeting tools like pay-as-you-go rules, a presidential line-item veto, a balanced budget amendment, and a ban on earmarks. Mark was one of a small group of senators who pushed for the creation of the president’s commission on reducing the national debt, and he now is helping lead the effort to hold an up-or-down vote on the commission’s recommendations.
Regarded as a national leader on renewable energy, Mark worked to put Colorado at the forefront of sustainable energy development. In 2004, he successfully co-chaired the Amendment 37 campaign to pass Colorado’s first Renewable Electricity Standard (RES), which requires power companies to use more alternative energy sources. In 2007, the House of Representatives twice passed a national renewable electricity standard championed by Mark. He continues his work in the Senate to enact a national RES.
Finally, Mark is also known for his efforts to develop a tough and smart national security strategy. He has led legislative action to strengthen the U.S military, improve national security and protect our service members by reducing the military’s reliance on fossil fuels. Moreover, he has consistently fought for programs to benefit our nation's veterans, including extending TRICARE benefits to military children and fighting to improve access to health care in rural Colorado.
Mark has received numerous accolades in the media. The Denver Post notes that he has a proven track record of bipartisan accomplishments. Al Lewis of the Dow Jones Newswires applauds Mark and his willingness to tackle America's most difficult challenges alongside members of both parties. The Grand Junction Daily Sentinel calls him “conscientious,” “highly capable” and “energetic.”
Mark was born on July 18, 1950, in Tucson, Arizona, but has spent his entire adult life in Colorado. After graduating from Williams College in 1972, he moved to Colorado's Western Slope and began a long and successful career with the Colorado Outward Bound School as a course director and educator from 1975-85 and as the organization’s executive director from 1985-95. Mark is an avid mountaineer and has climbed or attempted some of the world’s most challenging peaks, including Mt. Everest.
Mark’s family is no stranger to public service. His father, Morris “Mo” Udall, served in the U.S. House of Representatives for 30 years and ran for the Democratic nomination for President in 1976. His uncle, Stewart, was widely revered for his accomplishments while serving as Secretary of the Interior under U.S. Presidents Kennedy and Johnson. In 2008, Mark’s cousin, Tom Udall, was elected to the Senate from New Mexico.
Mark and his wife, prominent attorney and conservationist Maggie Fox, have two children: a son Jed and a daughter Tess. They live near Eldorado Springs in Boulder County.

In Congress, passing common-sense legislation can seem like a battle between David and Goliath. In this case, Goliath is deep-pocketed special interest groups that use their influence to block bills before they can get a vote. David is Colorado small businesses that just need more loan options so they can...

Truth be told, I'm much more comfortable in a pair of hiking boots or with a rack of climbing gear than in front of a laptop. But just like you, I know the Internet has opened countless doors for people seeking to educate themselves, start a small business, and communicate...

Today we will finally put an end to a discriminatory military policy that was crafted almost two decades ago during a time when we weren't at war with another country, but rather we were bitterly divided -- politically and socially -- against ourselves.

I think most Americans would agree people should be treated equally and everyone ought to be able to pursue a fulfilling life with the ones they love. But at times we fail to live up to the solemn promise guaranteed to every American in the Declaration of Independence, namely, life,...

I want to share a few thoughts about how Congress is working, or isn't working, and our country's direction.
I spent most of last week touring local businesses in my home state of Colorado, talking directly with people and hearing about what's going on in their lives and communities. Not...

Members of Congress are about to vote to extend the most controversial provisions of the USA PATRIOT Act for four more years, even though few of them understand how those provisions are being interpreted and applied.
As members of the Senate Intelligence Committee we have been provided with the executive...

Today marks the one-year anniversary of enacting the Affordable Care Act, the health-insurance reform bill I fought hard to pass in the 111th Congress to ensure Coloradans -- not their insurance companies -- can call the shots on their health care decisions. Equally important, it will enable many Coloradans to...

I've been in the Senate for two years, and while I'm proud of what we've been able to accomplish, I've developed a keen frustration with one thing in particular: the filibuster.
Don't get me wrong: I have a deep respect for the Senate, and I also realize that the winds...

Last month a federal court judge ruled that "Don't Ask, Don't Tell" (DADT) is unconstitutional. It was a huge step forward. But now the Department of Justice (DOJ) has the option to appeal this ruling and turn back the progress we have made.
Senator Kirsten Gillibrand of New York and...

Finally, we have a bill.
Just minutes ago, I stood with Senators Lieberman, Levin, Gillibrand, and Burris at a press conference and announced that we would be introducing the Military Readiness Enhancement Act of 2010 in the Senate to repeal the "Don't Ask, Don't Tell" policy.
In a time of...

The public option will provide much-needed competition and choice for health care. And with the majority of Senators, Representatives, and the American people supporting a public option, its passage would seem inevitable.
But in fact, the public option is in real danger.
That's because the quiet threat of...
