Casey had other ideas. Instead, the two-term senator has relentless criticized and hectored the new president and his team over everything from Team Trump's ties to Russia to cutting billionaires' taxes while "decimating" health care. When Trump's new Environmental Protection Agency chief Scott Pruitt questioned the conventional science on whether carbon dioxide is a pollutant, Casey and his young and energetic social-media team, tweeted, "We should probably leave this to, you know, actual scientists, but since you asked. Yes, it is." But the senator has also opposed Trump irl (in real life), voting against his controversial Cabinet nominees and expressing wariness on Sunday about Supreme Court pick Neil Gorsuch, whom he accused of favoring corporations over workers.
