A Russian company charged in special counsel Robert Mueller's investigation is complaining that his legal team is taking too long to hand over evidence in the case, according to a report published Wednesday by Reuters.

Eric Dubelier, the defense attorney representing the company Concord Management and Consulting LLC, exchanged heated words with prosecutors in federal court over the handling evidence, at one point saying it was "absolutely false" for the Mueller team to claim that he had hung up during a phone call on Friday.

"Any suggestion in that regard is absolutely false - it is demonstrably false," Dubelier said, according to Reuters. "I resent the implication that the special prosecutor made in court that I would hang up the phone on somebody. I didn't do it."

Concord, one of the three companies and 13 individuals indicted by Mueller's team in February, was charged with funding an operation meant to create strife in the American political system through the use of fake social media accounts.

The company has pleaded not guilty and President Trump has repeatedly said there was no collusion between his campaign and Russia.

The government disclosed that it has two terabytes of evidence in the form of social media profiles.

However, Dubelier has complained that the data has yet to be turned over and said the data will likely be in Russian and inconsequential to the case, Reuters reported. He added that his client did not make the social media profiles.

Prosecutors said the propaganda campaign aimed to help Trump's presidential campaign while hurting Hillary Clinton's Democratic campaign.

They also alleged that the company is owned by Russian businessman Evgeny Prigozhin, who has ties to Russian President Vladimir Putin.

The next hearing for the case will be held on June 15.
