The White House immigration meeting convened yesterday by President Trump was valuable and extraordinary. We learned a lot about three things -- the importance of transparency to the process, Trump's mental state, and the unfairness of the left/right media. Not everything that Trump wants in return for protecting DACA recipients will be good for the country. But meetings like this are a good thing, and Trump did a good job of defining and pushing his agenda. Anyone who said otherwise wasn't paying attention.
