On a Morning Joe interview that aired on Tuesday morning, Democratic presidential front-runner Joe Biden responded to questions about House Speaker Nancy Pelosi’s handling of the ultra-liberal group of freshmen lawmakers known as “the squad.” Biden said he believed that Pelosi was “masterful” in her work, but further heaped high praise on Alexandria Ocasio-Cortez, saying, “I think the freshmen, particularly AOC, is smart as hell.”

Biden’s response on Tuesday comes the morning after Ocasio-Cortez, along with three other female freshman lawmakers condemned the weekend tweets by President Trump in which he said if the congresswomen were unhappy with the United States they should, “go back and help fix the totally broken and crime infested places from which they came.”
