1. Big 3 to D.C.: President Trump is hosting a breakfast meeting with the CEOs of General Motors (GM), Ford (F) and Fiat Chrysler (FCAU) on Tuesday.

"[Trump] looks forward to hearing their ideas on how we can work together to bring more jobs back to this industry in particular," White House spokesman Sean Spicer said.

Executives from Toyota (TM), Honda (HMC), Nissan (NSANF) and Hyundai, which all have U.S. plants as well as plants in Mexico, weren't invited to this meeting, according to spokespeople from those companies.
