Jack Dorsey is set to tell Congress this week Twitter "does not use political ideology to make any decisions," according to prepared written testimony posted Tuesday by the House Committee on Energy and Commerce.

"We believe strongly in being impartial, and we strive to enforce our rules impartially," Dorsey said in the written testimony. "In fact, from a simple business perspective and to serve the public conversation, Twitter is incentivized to keep all voices on the platform."
