The feds are investigating whether a shady Russian banker linked to the Kremlin illegally funneled cash to the National Rifle Association to help Donald Trump win the election, McClatchy news reported Thursday.

FBI investigators are scrutinizing Alexander Torshin, the deputy governor of Russia’s central bank who is known to be tight with both Russian strongman Vladimir Putin as well as the NRA, the news service reported, citing sources.

It would be illegal for the NRA — which donated $30 million to Trump’s campaign, the highest amount the group ever spent on a presidential race— to spend foreign money to influence federal elections.

It’s unclear how long the Torshin inquiry has been going on, and the McClatchy report offered no specifics on what if any evidence the feds have uncovered.

But the revelation came as Special Counsel Robert Mueller’ probe of Russian interference in the election and possible ties to the Trump campaign appears to be rapidly progressing, with ex-Trump adviser Steve Bannon set to be interviewed.

The NRA did not immediately return requests for comment.

The pro-gun rights group reported spending a record $55 million on the 2016 elections, including $30 million to support Trump – triple what the group devoted to backing Republican Mitt Romney in 2012.

And most of that cash was spent by an arm of the NRA that is not required to disclose its donors, the news service said.

During the campaign, Trump was a staunch advocate of the Second Amendment, and drew heat for suggesting that if Clinton were elected, gun owners could stop her from appointing liberals to the Supreme Court.

“If she gets to pick her judges, nothing you can do folks,” Trump said at a rally in August 2016. “Although the Second Amendment people, maybe there is, I don’t know.”

Trump also spoke to addressed the NRA convention, and told members that “The eight-year assault on your second amendment freedoms has come to a crashing end.”

Torshin, a leading figure in Putin’s party, has been implicated in money laundering by judicial authorities in Spain, as Bloomberg News reported in 2016.

Spanish investigators alleged in a 500-page report that Torshin was a godfather in a major Russian criminal organization called Taganskaya.

At the NRA’s meeting in Kentucky in May 2016, Torshin also spoke to Donald Trump Jr. during a gala at the group’s national gathering.
