The New York Times reports:
A coalition of 16 states, including California and New York, on Monday night challenged President Trump in court over his plan to use emergency powers to spend billions of dollars on his border wall.
The suit, filed in Federal District Court in San Francisco, argues that the president does not have the power to divert funds for constructing a wall along the Mexican border because it is Congress that controls spending.
Joining California and New York are Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Michigan, Minnesota, Nevada, New Jersey, New Mexico, Oregon and Virginia. All have Democratic governors but one — Maryland, whose attorney general is a Democrat — and most have legislatures controlled by Democrats.
The lead sponsor of the suit is California AG Xavier Beccera.
