Former President Obama said Saturday he's concerned about progressives who are unwilling to compromise because it risks weakening "the overall effort and movement."
What he's saying: "One of the things I do worry about sometimes among progressives in the United States ... is a certain kind of rigidity where we say, 'Uh, I'm sorry, this is how it's going to be,' and then we start sometimes creating what's called a circular firing squad, where you start shooting at your allies because one of them is straying from purity on the issues," said at an Obama Foundation town hall event in Berlin, Germany.
