In comments posted by the press service of his Concord catering firm on Russia's Facebook equivalent VKontakte, Prigozhin said: "We have interfered (in U.S. elections), we are interfering and we will continue to interfere.
Carefully, accurately, surgically and in our own way, as we know how to do.".
The remark was posted on the eve of the U.S. midterm elections in response to a request for comment from a Russian news site.
"During our pinpoint operations, we will remove both kidneys and the liver at once," Prigozhin said.
In July, the U.S. State Department offered a reward of up to $10 million US for information on Prigozhin in connection with "engagement in U.S. election interference."
In September, he admitted to founding the Kremlin-aligned Wagner Group mercenary organization, which is active in Syria, Africa and Ukraine.
Last Friday, it opened a defence technology centre in St. Petersburg, a further step by Prigozhin to highlight his military credentials. »
