DES MOINES, Iowa, Sept 22 (Reuters) - U.S. Democratic presidential candidate Hillary Clinton said on Tuesday she would release a plan in the next few days for a clean energy agreement among the United States, Canada and Mexico.
"I will also be putting out in the next few days a broad approach to how I would work to have a North American compact about clean energy," Clinton told the Des Moines Register editorial board, after announcing earlier on Tuesday her opposition to the proposed Keystone oil pipeline.
