Why it matters: It's unclear how Sessions' decision would impact marijuana sales, which is legal on the state level in eight states and Washington, D.C., for recreational use and in 29 states, including the District, for medical purposes.

Why it matters: In his quest to build affordable electric cars for the masses, Musk is starting to embrace many of the ideas pioneered by Ford's founder — things like vertical supply chains and an obsession with manufacturing efficiency. A century ago that approach helped to popularize the American automobile by lowering the cost of the Model T.
