A top House committee that oversees the U.S. telecommunications industry is now reviewing whether Twitter CEO Jack Dorsey lied to Congress during a hearing about Twitter’s controversial history of arbitrarily censoring content published by the site, an aide for the House Energy and Commerce committee told The Federalist.

“The committee is aware of Twitter’s actions and is currently reviewing Mr. Dorsey’s testimony,” the aide said after Twitter suddenly banned Jesse Kelly, a Marine combat veteran, writer, and popular radio talk show host, without explanation.
