National security adviser John Bolton recently chaired a nonprofit that has shared fake anti-Muslim news, according to a new report.

Bolton was chairman of the New York-based Gatestone Institute, which peddled misleading and false anti-Muslim accounts, from 2013 until he resigned last month, NBC News reported.

The advocacy group warns about an imminent “jihadist takeover” of Europe that will lead to a “Great White Death,” according to the report.

Among the headlines appearing on the institute’s website last year is “Germany Confiscating Homes to Use for Migrants” — about one apartment rental property in Hamburg that landed in a temporary trusteeship.

Another from 2015 claimed immigrants such as Somalis in Sweden were turning that country into the “Rape Capital of the West.”

Gatestone is “a key part of the whole Islamaphobic cottage industry on the internet,” Ibrahim Hooper, spokesman for the Council on American-Islamic Relations, told NBC News.

Bolton’s affiliation with Gatestone “and in one of the most powerful positions on the planet, is very disturbing,” Hooper said.

The institute says on its website that it is a nonpartisan group “dedicated to educating the public about what the mainstream media fails to report” on a range of topics, including human rights and free speech.

Brookings Institution fellow Alina Polyakova, who studies far-right populism, told NBC that Gatestone is “putting out content that was clearly anti-immigrant, anti-Muslim and was echoing some of the Russian disinformation propaganda” being spread by internet trolls.

Bolton, a hardline hawk and former UN ambassador, formally started as national security adviser in early April after being tapped by President Trump to replace H.R. McMaster. He has continued to meet with White House attorneys over possible conflicts of interest.

The US National Security Council said it does not respond to inquiries about outside organizations but confirmed Bolton is aware of the NBC News story.
