CNBC’s Phil LeBeau reports on the demands from both sides, and The Wall Street Joural’s Tim Higgins explains how Elon Musk’s Tesla is involved (by not being involved), as well as President Biden’s role. Former Microsoft CEO Steve Ballmer, now founder of USAFacts, discusses DC’s recent tech and political summit on AI and innovation’s regulatory framework.
