Joan Walsh, national affairs correspondent for The Nation and a political analyst at CNN, discusses the latest news coming out of Washington, including news that President Trump's top economic advisor Gary Cohn will resign, Trump's tariffs and the federal government's lawsuit against the state of California over its immigration policies. Plus Evan Smith, CEO and co-founder of The Texas Tribune, discusses the results of the primary election in Texas -- and what they signal for the upcoming midterm elections.

Cohn left when he lost tariffs. Stayed when Trump said there were “very fine people” at neo-Nazi rally. Good moral observation from @joanwalsh on @BrianLehrer

@TexasTribune's @evanasmith says Republicans turned out about half a million more voters than Democrats. It's a better margin for Dems than they have gotten in the past. But idea that there is a Democratic "tsunami" coming is "really not visible necessarily."

@TexasTribune's @evanasmith says "the wave in Texas yesterday was not blue, it was pink." If you were a woman running, you had a good day.
