In the article it says:
I’m unfamiliar with the expression “tinfoil hat” and a few usually knowledgeable friends I called were also unfamiliar with it. But for it to be on the cover of a weekly news magazine it must be fairly popular – it must somehow have passed me by. Sure enough it is in most online dictionaries and a news search seemed to indicate that it is fairly widely used.“Ron Johnson last week jumped on a report that two FBI agents had mentioned a “secret society’ in text messages to warn Americans that FBI agents were ‘holding secret meetings off site —presumably to plot against the president. The next day, Johnson backed off his claim when it became clear the ‘secret society’ reference in the texts was a joke. Nonetheless, Sean Hannity and other Fox News anchors stayed in ‘full tinfoil-hat mode,’ delivering fevered nightly calls for the purging, and jailing, of anti-Trump conspirators. What’s more disturbing said Michael Gerson in the Washington Post, is that even mainstream Republicans, including House Speaker Paul Ryan, are echoing Hannity’s calls to ‘cleanse’ the FBI.”

A piece of headgear made from one or more sheets of tin foil, aluminium foil, or other similar material, especially when worn in the belief that it shields the brain from electromagnetic fields, or against mind control and/or mind reading.
tin foil Hat: A tin foil hat is a hat made from one or more sheets of aluminium foil, or a piece of conventional headgear lined with foil, worn in the belief or hope that it shields the brain from threats such as electromagnetic fields, mind control, and mind reading. The notion of wearing homemade headgear for such protection has become a popular stereotype and byword for paranoia, persecutory delusions, and belief in pseudoscience and conspiracy theories.
Origin: An early allusion to an "insulative electrical contrivance encircling the head during thought" appears in the unusual 1909 non-fiction publication Atomic Consciousness by self-proclaimed "seer" John Palfrey (aka "James Bathurst") who believed such headgear was not effective for his "retention of thoughts and ideas" against a supposed "telepathic impactive impingement". For further details see tin foil hat.
