Former Breitbart News chief and President Donald Trump’s adviser Stephen Bannon has sparked a new movement of sorts on social media with #PostcardstoBannon and #PresidentBannon surfacing on Twitter over the past week.

Trump is reportedly not very happy with suggestions that it is his adviser who is calling the shots in the White House and took to Twitter on Monday to lash out at recent news reports that suggest a crisis within his administration.

“I call my own shots, largely based on an accumulation of data, and everyone knows it. Some FAKE NEWS media, in order to marginalize, lies!” Trump tweeted.

Trump attacked a New York Times report that showed the friction inside the president’s administration, even mentioning names of many of his top advisers. “The failing @nytimes writes total fiction concerning me. They have gotten it wrong for two years, and now are making up stories & sources!” Trump said.

The hashtag #PresidentBannon gained ground last week after Bannon was appointed to the National Security Council by an executive order signed by Trump. This decision came at a time when the country was still reeling under the effects of the president’s temporary travel ban on people from seven Muslim-majority countries as well as the suspension of the refugee program.

Bannon’s rise was also the theme of Saturday Night Live’s cold open last week as Alec Baldwin, playing Trump, is informed that daughter Ivanka and son-in-law Jared Kushner are not present as they “don’t work on Shabbat.”

“When the Jews are away, the goys will play. Send in Steve Bannon,” he says, before a Grim Reaper-looking version of Bannon enters the room. Watch the clip below:
