A new report from Harvard University says press coverage of Donald Trump’s presidential campaign become progressively more negative as Trump built a lead in the Republican primaries — and soared after Trump clinched the GOP nomination.

A graph in the report from the Shorenstein Center of Media, Politics and Public Policy forms an almost perfect “X,” as Trump coverage went from 57 percent positive and 43 percent negative during the early Republican primaries to 61 percent negative and 39 percent positive after Trump defeated his last Republican rivals.
