I’m proud to stand up for our farmers and producers as a @GrowthEnergy Biofuels Champion. Our biofuels provide good-paying jobs and the clean energy that keeps America running — when they’re strong, Iowa is strong. #IA01 https://t.co/96cepXXW0T

Representative @daveloebsack took time to advocate for biofuels in the House Committee for Energy and Commerce yesterday. We need oversight like this to ensure gap-filings from the oil industry don't become another source of harm for our producers. Thank you, Congressman! https://t.co/JRDYxzgq67

One of the biofuel industry's greatest allies in Congress over the last two years has been @RepFinkenauer, and Growth Energy CEO @EmilySkor sat down with her recently as part of our Biofuels Champions Series. Keep up the good work, Congresswoman! youtu.be/7La8pHuKyVc

I spoke with @GrowthEnergy about the need for everyone to understand just how important renewable fuels are for Iowa's farmers and our nation. WATCH: https://t.co/Ik7Eu4Iry0
