CNN first reported on the scripted message in early March, noting that despite many anchors' dismay, the "anchor-delivered journalistic responsibility message" would begin to run on Sinclair stations later in the month. "This is extremely unsafe to a democracy".
Dozens of stations belonging to the nation's largest broadcaster have aired video promotions in the last few weeks in which their local on-air news hosts voice concerns about "the troubling trend of irresponsible, one-sided news stories plaguing our country".
Sinclair owns almost 200 stations, including KBOI in Boise, KLEW in Lewiston and KIDK in Idaho Falls.
The president came to the company's defense Monday, since they're a big cheerleader for him.
Several local reporters have reportedly spoken out since the news broke, saying they were uncomfortable with being forced to recite a script echoing Trump's inflammatory remarks about so-called "fake news". Researchers Gregory Martin and Josh McCrain recently published a paper that showed Sinclair-owned stations focused more on national news, which tends to be more politically charged. In a sign of Sinclair's controversial stature, Deadspin's compilation of the promos - making the anchors in various markets sound like robots - went viral on Saturday.
Critics have complained that Sinclair orders its local stations to air "must-run" segments with what they describe as a rightward slant, including frequent reports from a "Terrorism Alert Desk".
Deadspin received a hat tip from HBO's John Oliver, whose "Last Week Tonight" did a lengthy story on Sinclair last season.
Most of Sinclair's stations are CNN affiliates - meaning CNN shares content and resources with them and vice versa. "We've asked people to voice their opposition to Sinclair's plan to merge with Tribune Media, which has yet to be approved".
The video was widely circulated and caught the attention of news media professionals as well as celebrities like Jimmy Kimmel who shared the video to an even wider audience.
Ultimately, how can a press remain free and objective when those who are put in control of it are most interested in profit and advancing a political agenda?
Democrats have also chided FCC Chairman Ajit Pai, a Trump-appointed Republican, for supporting TV ownership rule changes that would make it easier for the merger to pass regulatory scrutiny.
