HONOLULU (HawaiiNewsNow) - U.S. Sen. Brian Schatz will back former Secretary of State Hillary Clinton in a possible 2016 presidential campaign, he announced Monday. "Given our shared passion for addressing challenges like climate change and promoting policies to strengthen America's future generations, I am encouraging Hillary Clinton to run for president, and I'm ready to support her the moment she announces her decision," Schatz said in a statement. Clinton has not yet declared her run for president, but it is suspected that she will run. She previously ran against President Barack Obama in 2008. Schatz, who has been at the forefront of environmental issues, said he's supporting Clinton because of the way she addresses climate change. "As a U.S. Senator and Secretary of State, Hillary Clinton's commitment to protecting our country and our planet from the threat of climate change was both genuine and deep," he said. "Secretary Clinton literally changed the way America approaches climate change, putting global warming at the center of U.S. foreign policy, holding other nations and their leaders accountable for their carbon emissions, and even appointing a Special Envoy for Climate Change at the State Department." Schatz also encouraged his supporters to sign join him in the national grassroots effort, Ready for Hillary, by visiting readyforhillary.com.
