DONALD Trump has been accused of fuelling "dangerous"conspiracy theories by regularly retweeting the posts of QAnon fanatics.

Critics say the Twitter-loving US president is offering far right crackpots badly-needed proof their ludicrous suspicions about the establishment are actually true.

The QAnon theory centres on an anonymous online individual - known only as Q - who claims to be a government official with info about a covert plot to overthrow Trump.

Followers of the bizarre conspiracy believe that, among many other things, the world is run by a satanists and paedophiles.

They say the "cabal" is led by Democrats and the so-called deep state and believe Trump - with help from Robert Mueller - will eventually expose and defeat it.

However, earlier this year the FBI designated QAnon a possible domestic terrorism threat as it believes its messages are so unhinged.

Despite the warning, last week Trump, or someone with access to his account, retweeted a message containing the hashtag 'WWG1WGA' - the QAnon motto 'Where we go one, we go all.'

In total, Trump retweeted QAnon fans more than 20 times on the same day.

“It draws more eyes,” Roy Davis a well-known QAnon promoter known to believers as 'Captain Roy ' told The Daily Beast.

And it wasn’t the first time Trump has pushed bizarre theories to his 68 million followers.

According to a New York Times investigation published in November, he has retweeted at least 145 unverified accounts that have promoted unproven theories.

What is QAnon and how did it start? In late October 2017, an anonymous user going simply by 'Q' posted on 4chan, a shadowy site known for, among other things, cruel hoaxes and extremism. This person claimed to be a government insider who had access to classified information into both the Trump administration and his political opponents. He or she gives readers "breadcrumbs" so they arrive at their own conclusions while using special lingo so these amateur sleuths feel like they are part of a club. Q has ludicrously claimed special counsel Robert Mueller is secretly investigating Clinton and Obama who are planning a coup while involved in a child sex ring. It's also claimed the US created North Korea and installed a "madman" puppet leader to stop the world from falling into nuclear Armageddon

Over two dozen of these accounts were later suspended by Twitter for violating the platform's strict rules.

Many QAnon followers point to Trump's retweets as vital proof their unproven fears about the establishment are genuine.

“They certainly also get encouraged by Trump repeatedly retweeting QAnon accounts,” said Travis View, a podcaster who tracks QAnon’s reach.

“They claim that Trump would never retweet pro-Q accounts if there was nothing to Q.”

The theories gained huge press coverage after a supporter held a vast letter Q at a Trump rally in Pennsylvania in August 2018.

Then an armed QAnon follower blocked traffic at the Hoover Dam, demanding the president release a report allegedly tying past presidents to the alleged paedo ring.

The bizarre theory quickly gained cult status among some followers, with Q-related products such as T-shirts, mugs and jewellery now for sale online.

And conservative celebrities such as Roseanne Barr and Curt Schilling have also referenced its existence, giving it yet more global exposure.
