The report examined 1,065 network evening news stories about Trump and key members of his administration. The MRC had looked at broadcast evening news reports of Trump from January 1 through April 30 and "found 90 percent of the evaluative comments about the president were negative".
Last fall, the Media Research Center released a study citing that figure after evaluating the nightly newscasts on ABC, CBS and NBC during the summer.
"The liberal media's war against President Trump was as fierce as ever during the first four months of 2018, but the onslaught appears to be for naught", the study found.

Trump particularly targets CNN, where one of its on-air personalities, Chris Cuomo, once said "I see being called "fake news" as the equivalent of the n-word for journalists", though he later apologized for the comparison.
"The mop-up on this issue is going to be excruciating.", he added. During his 2016 campaign he blacklisted reporters from several outlets, including Politico, The Daily Beast and the Huffington Post, from his rallies.
A stricter licensing system of White House reporters under Trump would presumably be good for Drudge, who has gained close access under the current president.
