A "Frank" Contradiction?

Yesterday, I received Rep. Wolf's newsletter and saw Wolf bragging that "On Tuesday Congress cleared an energy bill, with my support..." Can someone please help me resolve the apparent contradiction between that statement and this (Wolf voting against an amendment "to move the United States toward greater energy independence and security, to increase the production of clean renewable fuels, to protect consumers, to increase the efficiency of products, buildings, and vehicles, to promote research on and deploy greenhouse gas capture and storage options, and to improve the energy performance of the Federal Government") and this (Wolf's anti-environment history)?

Is this a "Frank" contradiction or what? I'm confused.
