Transportation Secretary Pete Buttigieg on Sunday defended President Joe Biden's economic policies, saying the Biden administration's "top economic priority" is fighting inflation amid rising costs in food, housing and health care.  But Buttigieg also touted the administration's COVID-19 recovery package, which he credited with having "rescued the economy" and said without it, "we would not have had the 10 million jobs created with this president with the lowest unemployment numbers in history." "Look, I don't think anybody could argue that, for example, our unemployment numbers are anything but strong as hell," he said later in the interview.  But more than two-thirds of registered U.S. voters say the Biden administration could be doing more to address inflation and the price increases that have come with it, according to the latest CBS News Battleground Tracker poll, which pointed to slowing momentum among Democratic congressional candidates after months of steady advances.
