Three key mainstream media outlets lavished President Donald Trump (pictured above) with 92 percent negative coverage from June 1 to September 30, according to a study released Tuesday by the Media Research Center (MRC).

“In four weeks, Americans go to the polls for the midterm elections that the news media are casting as a referendum on the Trump presidency,” MRC Research Director Rich Noyes wrote Tuesday.

“Over the summer, the broadcast networks have continued to pound Donald Trump and his team with the most hostile coverage of a president in TV news history — 92 percent negative, versus just 8 percent positive,” Noyes noted.

MRC analysts evaluated 1,007 evening news broadcasts spanning a total of 1,960 minutes from ABC, CBS and NBC over the four-month period.

The study showed that almost two-thirds of the networks’ evening reports covered five topics: Supreme Court Justice Brett Kavanaugh’s confirmation process, special counsel Robert Mueller’s continuing investigation into allegations of collusion between Trump campaign officials and Russia, the United States’ relationship with Russia, the Trump administration’s diplomatic efforts with North Korea, and Trump’s overall immigration policies.

The Russia probe earned 342 minutes of coverage that was slanted 97 percent negative, whereas Trump’s immigration policies received 308 minutes of 94 percent such coverage, MRC found.

The Trump administration’s handling of Kavanaugh’s nomination — including how White House officials addressed the last-minute sexual assault allegations leveled against him — received 291 minutes of 82 percent negative coverage.

The president’s North Korean diplomacy efforts earned 179 minutes of 90 percent negative coverage, while U.S.-Russia relations received 151 minutes of 99 percent negative coverage.

The American economy is booming, but ABC, CBS and NBC viewers probably don’t know it because the three broadcast networks spent less than 1 percent of their evening news coverage during that four-month period focusing on the Trump administration’s accomplishments, such as record low unemployment and rapid jobs growth.

“The Fake News Media is desperate to distract from the economy and record setting economic numbers and so they keep talking about the phony Russian Witch Hunt.”

The negative statements MRC analysts recorded came from so-called nonpartisan sources including reporters, anchors, and topic experts — not partisan talking heads.

The Trump administration earned an average of 90 percent negative coverage during its first year in office across the several MRC studies carried out in 2017. An MRC study released in May found similar results to the most recent study, with 91 percent negative coverage.

Trump has long railed against the mainstream media for their negative coverage of himself and his administration, calling the outlets “Fake News” and “The Enemy of the People.”

“The Fake News Media is desperate to distract from the economy and record setting economic numbers and so they keep talking about the phony Russian Witch Hunt,” the president tweeted on June 4.

“I just cannot state strongly enough how totally dishonest much of the Media is. Truth doesn’t matter to them, they only have their hatred & agenda. This includes fake books, which come out about me all the time, always anonymous sources, and are pure fiction. Enemy of the People!” Trump tweeted on August 30.

MRC studies have found that Trump’s negative media coverage percentage remains relatively constant in the 90s, and Trump himself claimed in August that the coverage was about 80 percent slanted against him.

“And the fake news is comprised of — it’s a lot. It’s a big chunk, okay? Somebody said, ‘What’s the chunk?’ I said, ’80 percent,'” Trump told “Fox & Friends” co-host Ainsley Earhardt. “It’s a lot. If I do something well, it’s not reported. Other than in the 20 percent.”
