Rethinking The I-90 Interchange; Sen. Rosenberg

Host Meghna Chakrabarti talks about what might happen to Sen. Stan Rosenberg after new allegations this week about his husband's involvement in government affairs. And we talk about the Allston 1-90 Interchange Improvement project and how some want to completely rethink "the throat." Plus: WBUR's Zeninjor Enwemeka on the effects of Uber and Lyft on traffic — and what Chicago is doing about it. And Bill Littlefield of NPR's Only A Game has the latest on the Olympics and the Patriots. Finally, an update on Steve Wynn, who resigned from his post as CEO of Wynn Resorts on Tuesday.
