Americans' overall trust in the media has declined since last year and is plummeting among self-identified Republicans, according to a new survey from Morning Consult and The Hollywood Reporter.

The share of self-identified Republicans who find nine leading news outlets to be credible decreased by 12 percentage points, from 56% to 44%, since 2016.

CBS was perceived as credible by a high percentage of American adults, Democrats found ABC to be the most credible, and Fox News was the most credible among Republicans.

Americans' overall trust in the media has declined since last year and is plummeting among self-identified Republicans, according to a new survey from Morning Consult and The Hollywood Reporter.

The survey, conducted among more than 2,000 American adults from March 28 to April 2 of this year, comes as President Donald Trump is ramping up the critical rhetoric about the press that he's used throughout his presidency.

Morning Consult said Trump has complained about "fake news" on Twitter 400 times since November 2016 and numerous other times during public appearances.

The survey asked respondents whether they believed the leading broadcasters CBS, ABC, and NBC; the cable news channels MSNBC, CNN, and Fox; the print outlets The New York Times and The Wall Street Journal; and National Public Radio (NPR) are credible.

While trust in the media has declined among all groups, the researchers said Trump's comments seem to be having the most significant influence on media credibility among Republicans, with the share of self-identified Republicans who find those nine news outlets credible decreasing 12 percentage points, from 56% to 44%, since 2016.

The survey also found that CNN and The New York Times — two of the outlets Trump attacks most frequently — have experienced the biggest drop in credibility among Republicans, falling by nearly 20 percentage points since 2016.
