Actor Kevin Costner is smitten with Liz Cheney and her increasingly acerbic attacks on President-elect Donald Trump, saying the former Republican congresswoman from Wyoming should be applauded for her public service in branding him “unstable,” “depraved,” and “cruel” amongst other insults. “I expect people in government to do the right thing. Public service is about public service. It’s not about your career. It’s not about your ego. Your four years is your four years,” the former Yellowstone star said Monday during a live, town-hall edition of “The Michael Smerconish Program” on SiriusXM.
