One America News Network (OANN), also known as One America News (OAN), is a far-right, pro-Donald Trump cable channel founded by Robert Herring Sr. and owned by Herring Networks, Inc., launched on July 4, 2013. The network is headquartered in San Diego, California, and operates news bureaus in Washington, D.C. and New York City.

Its prime time political talk shows have a conservative perspective, and the channel has described itself as one of the “greatest supporters” of President Donald Trump. Trump himself has promoted the network.

The channel is prominent for promoting falsehoods and conspiracy theories.

OAN is known for downplaying threats posed to the United States by Russia. According to a former OAN producer, on his first day at OAN he was told, “Yeah, we like Russia here.” One of OAN’s reporters, Kristian Brunovich Rouz, simultaneously works for the Russian propaganda outlet and news agency Sputnik, which is state-owned; when Rouz runs favorable segments on OAN that relate to Russia, OAN does not disclose that he also works for Sputnik.

In September 2019, OAN parent Herring Networks filed suit in federal court in San Diego, California, against MSNBC host Rachel Maddow for $10 million after Maddow said the network “literally [is] paid Russian propaganda” on her July 22, 2019 program. Maddow had referenced a Daily Beast story identifying Rouz as also working for Sputnik. Also named in the suit were Comcast, MSNBC and NBCUniversal Media. A hearing on a motion to strike brought by Maddow was originally scheduled for March 2020, but due to the COVID-19 pandemic, the arguments were moved to May 2020 by Judge Cynthia Bashant. The judge dismissed the lawsuit, finding the claim was not defamation, but that a “reasonable viewer” would recognize it as a reasonable summation of the article published by The Daily Beast. OAN responded by saying it would appeal the decision.
