Early Uber investor Bradley Tusk on why he's selling some shares
Uber co-founder Travis Kalanick has been on a selling spree since Uber's lockup expired of Nov. 6, selling nearly $1.5 billion worth of stock since then, including more than half a million just this week. This comes as CEO Dara Khosrowshahi spent nearly $7 million on purchasing shares. Bradley Tusk, founder and CEO of Tusk Ventures and an early Uber investor, and Craig Hatkoff, co-founder of the Disruptor Foundation, join "Squawk Box" to discuss.
