In a rare interview with Fox News, President Obama admitted what he believes is his worst mistake. Wallace was doing what he called a “lightning round” of questions about the president’s time in the White House. “Worst mistake?” Wallace asked. “Probably failing to plan for the day after for what I think was the right thing to do in intervening in Libya,” he told Chris Wallace. What makes that more poignant is that it was Hillary Clinton who served as secretary of state at the time and who pushed for the intervention, according to the Washington Free Beacon.
