Rinat Akhmetshin, the Russian lobbyist and ex-Soviet military intelligence officer who was at Donald Trump Jr.'s Trump Tower Russia meeting last June, has deep connections to the Kremlin.

He was involved in two hacking-related cases after working for Russian businessmen who were closely allied to Vladimir Putin.

Akhmetshin has also told reporters he is a "longtime acquaintance" of Paul Manafort, though Manafort's spokesman denied the claim.

Rinat Akhmetshin, the Russian lobbyist who was present at Donald Trump Jr.'s meeting with a Russian lawyer last June at Trump Tower, may have stronger links to the Kremlin than previously known, The New York Times reported Monday.

A former Soviet military intelligence officer, Akhmetshin has long been tied to Kremlin-linked individuals, but the new Times report has drawn connections between Akhmetshin and several high profile Russian billionaires, for whose companies he supposedly worked. The companies were embroiled in contentious legal battles during which their opponents made hacking allegations.

Further, the Times found that, in 2010, Akhmetshin began working with Viktor Ivanov, who used to be the deputy head of Russia's intelligence agency, the F.S.B., and who previously served as a top adviser to Putin.

In an affidavit Akhmetshin provided in one of the hacking cases, he said he had spoken to Ivanov about topics "from narco-trafficking and terrorism in Afghanistan to surveillance of undercover agents, suspected undercover agents and their identities."

The hacking cases

Akhmetshin has been associated in the past with corporations owned by multiple Russian businessmen with close ties to Russian President Vladimir Putin, and he was involved in two legal battles in which his associates' rivals were victims of sophisticated hacking operations.

In one case, Akhmetshin was tied to Russian billionaire Suleiman Kerimov, when Kerimov was involved in a dispute with competitor Ashot Egiazaryan.

Kerimov is a portfolio investor who is said to be tied to the Kremlin through his business dealings with individuals like Vladimir Kogan, a Russian tycoon who's been referred to as "Putin's banker." In March, Putin also awarded Kerimov the Order for Merit to the Fatherland of II.

During Kerimov's conflict with Egiazaryan in 2011, two British lawyers representing Egiazaryan received suspicious emails, sources familiar with the investigation told the Times. Forensic analysis of the emails determined that the messages contained malicious content meant to infect their computers. The emails originated from computers registered with one of Kerimov's companies in Moscow.

Later that year, Russia approved a warrant for Egiazaryan's arrest, based on charges of large-scale fraud. Egiazaryan is currently a fugitive and wanted by Interpol.

In 2013, Akhmetshin was directly accused of hacking in a separate case. At the time, Akhmetshin was consulting for a law firm representing EuroChem, a mining company owned by a Russian billionaire. The allegations against Akhmetshin claimed he was targeting International Mineral Resources.

A source familiar with the case told the Times that Akhmetshin had personally given a flash drive containing hacked documents to a lawyer "engaged in another matter potentially damaging" to International Mineral Resources. An investigator working for EuroChem's competitor also claimed he'd overheard Akhmetshin saying that he had paid Russian hackers "a lot of money" for the documents. Court filings reviewed by the Times indicate that the content on the flash drive was also accessed by someone with the initials, "R.A."

When Akhmetshin was questioned about those events during a deposition, he confirmed he had handed over a hard drive with information about International Mineral Resources, but claimed that the information had come from a Kazakh contact. He denied knowing anything about hacking and said he did not "know a single person who could do that."

IMR dropped its lawsuit against Akhmetshin in early 2016, the Times reported, and said in a statement that it dropped the charges "after careful consideration."

The June meeting

The June 2016 meeting at Trump Tower arranged by Donald Trump Jr. and its attendees are now being scrutinized by Robert Mueller, the special counsel in charge of the FBI's investigation into whether the Trump campaign colluded with Moscow to tilt the 2016 election in his favor.

Akhmetshin has told reporters that he took last June's Trump Tower meeting with Trump Jr. by chance. He said he was having lunch with Russian lawyer Natalia Veselnitskaya that day when she "spontaneously" invited him to the meeting.

For at least the last year, he has worked closely with Veselnitskaya to lobby against the 2012 Magnitsky Act, a US law that blacklists Russians accused of human rights abuses.

In addition, Akhmetshin has said that he is a "longtime acquaintance" of Paul Manafort, Trump's former campaign manager who was present at the meeting. Manafort was once a top adviser to Ukrainian President Viktor Yanukovych, a pro-Russian strongman whom Manafort is widely credited with helping win the presidency in 2010. Akhmetshin has told reporters in the past that he unsuccessfully tried to consult Yanukovych's pro-Russia Party of Regions before Russia invaded and annexed the Ukrainian territory of Crimea in 2014, according to the Times.

Manafort's spokesman, Jason Maloni, denied any relationship between his client and Akhmetshin. "More gossip and unconfirmable nonsense - Paul doesn't know and hasn't worked with the man," Maloni told Business Insider in response to the Times' investigation.

Manafort invited further scrutiny scrutiny after The Washington Post reported that the FBI conducted a predawn raid on his home in July. Agents working with Mueller left Manafort's home "with various records," according to The Post.

Manafort has been cooperating with investigators' requests for relevant documents. But the search warrant obtained by the FBI in July indicates that Mueller managed to convince a federal judge that Manafort would try to conceal or destroy documents subpoenaed by a grand jury.
