U.S. Transportation Secretary Pete Buttigieg said Wednesday the Biden administration could take further action against Russia after the administration announced it would bar Russian airlines from U.S. airspace.
"There may be other steps that would be appropriate that are within our authorities," Buttigieg told a U.S. Senate panel. "There are a number of things with regard to infrastructure and certainly with regard to travel that we need to look at as a way to make good on out commitment to support the Ukrainian people."
