The New York Times traced Trump’s statement to an inaccurate observation that morning by Brian Kilmeade, a co-host of one of Trump’s favorite TV shows, “Fox & Friends.” The survey by the online polling company SurveyMonkey found Trump’s black approval rating declined from 20 percent in February, his first full month in office, to 15 percent in December — which was consistent with polling by Pew Research Center and Reuters.
