WASHINGTON (AP) — Rep. Liz Cheney says she was wrong to oppose gay marriage in the past, a stand that once split her family. Cheney, R-Wyo., a fierce critic of fellow Republican Donald Trump, also tells CBS News’ “60 Minutes” that she views her reelection campaign as the most important House race in the nation as forces aligned with the former president try to unseat her. She voted to impeach Trump over his role in the Jan. 6 riot at the U.S. Capitol. In the interview aired Sunday night, Cheney said she had little affection for President Joe Biden, who she believes has embraced harmful policies for the economy and national security with the Afghanistan withdrawal. “But the alternative cannot be a man who doesn’t believe in the rule of law, and who violated his oath of office,” Cheney said. The daughter of former Vice President Dick Cheney was an ascendant Republican leader before the Jan. 6 riot, yet she is increasingly defined by her public opposition to Trump and his hold on the GOP. Cheney, 55, noted that she still talks with her father every night and that they share the same views on rejecting Trump. Liz Cheney famously broke with her family in 2013 by opposing gay marriage ahead of a failed Senate bid. Her objections caused a rift with her sister, Mary, a married lesbian. Mary’s spouse, Heather Poe, posted on Facebook that year that Cheney’s position was offensive and that “I always thought freedom meant freedom for EVERYONE.”
