In an interview that aired Saturday on CNN, Dorsey said his company has a responsibility to be open about its political viewpoints, but to operate without bias when applying content policies to users.

“We need to constantly show that we are not adding our own bias, which I fully admit is…is more left-leaning,” Dorsey says.

“But the real question behind the question is, are we doing something according to political ideology or viewpoints? And we are not. Period,” he added.
