When President Donald Trump angrily tweeted earlier this month that there was wiretapping going on in Trump Tower, he was not mistaken, as it turns out.

Between 2011 and 2013, the FBI had a court-approved warrant to monitor a Russian money-laundering ring that was operating out of unit 63A in Trump Tower, just three floors below the real estate mogul's gilded penthouse, reported ABC News.

The federal investigation led to an indictment of 30 suspects, many who whom were captured during a raid on their swanky Manhattan hideout, but the alleged mastermind of the criminal organization, notorious Russian mafia boss Alimzhan Tokhtakhunov, was able to slip away.

A few months after the April 2013 raid, the wanted fugitive resurfaced in the VIP section of Miss Universe Moscow, just steps away from Donald Trump.

Speaking to Mother Jones during the presidential campaign last year, Tokhtakhunov, who lives in Russia, said that he did not interact with Trump at the glitzy event.

Tokhtakhunov, 68, is perhaps best known for playing a key role in the bribery scandal that marred the 2002 Winter Olympics in Turin, when he was accused of paying off judges to vote in favor of the Russian pairs team.

He was briefly detained in Italy by request of US prosecutors but was eventually freed and returned to Russia.

In the decade after the Olympiad kerfuffle, Tokhtakhunov has allegedly cobbled together a $50million criminal organization focused primarily on mafia money laundering, sports gambling and extortion.

The home base of the underground syndicate was Trump Tower, according to the FBI.

During a raid on Trump Tower in 2013, the feds arrested dozens of suspects but Tokhtakhunov was able to slip away, only to resurface months later in the VIP section at Miss Universe in Moscow, not far from Donald Trump (pictured at the event)

‘Everything was moving in and out of there,’ said former FBI official Rich Frankel, now an ABC News consultant.

The two-year FBI investigation, which terminated in 2013, led to the arrest and conviction of top mafia operative Vadim Trincher, a professional poker player who is currently serving five years on racketeering charges.

Mother Jones previously reported that Trincher, who is a dual citizen of the US and Israel, had paid $5million in 2009 for the third-floor unit in Trump Tower, which became the nerve center of Tokhtakhunov’s money-laundering ring.

Thanks to the wiretapping warrant, the feds were able to intercept phone calls and text message exchanges between the various players in Tokhtakhunov’s felonious cabal operating out of Trum’s gleaming skyscraper in the heart of New York City.

President Trump was not implicated in the federal probe into the Russia crime ring.

After escaping the grasp of the FBI four years ago, Mr Tokhtakhunov, who is married and has five grown children, became the subject of Interpol's international 'Red Notice' indicating his status as a wanted man, facing charges of wire fraud and bribery conspiracy.

But his legal troubles abroad have not stopped Tokhtakhunov from regularly showing up at high-end restaurants in Moscow, where he owns property and runs various business ventures.

Shortly after a federal grand jury returned an indictment in 2013, Tokhtakhounov told a Russian TV station that the case against him was ‘yet another fairy tale from the Americans.'

During five hours of sworn testimony before House Intelligence committee on Monday, FBI Director James Comey declared there was no evidence to support Trump's extraordinary claim that President Barack Obama had his Manhattan skyscraper wiretapped.

Comey did confirm in the course of the bruising hearing, however, that the FBI has been investigating since the summer whether Trump's associates coordinated with Russian officials in an effort to sway the 2016 presidential election.

Tight-lipped for the most part, Comey refused to offer details on the scope, targets or timeline for the FBI probe.
