The White House on Tuesday voiced doubts about controversial California water legislation that has already caused an unusually public split between the state’s two Democratic senators. Meeting with reporters, White House spokesman Josh Earnest said the California provisions that span some 91 pages of often-technical text seemed problematic, though he cautioned that analysis continues. “Based on what we know so far, we don’t support the kinds of proposals that have been put forward to address some of the water resources issues in California right now,” Earnest said.
