The charging documents against Pinedo do not mention a connection with the Russian indictment but were released by Mueller's office shortly after that indictment was disclosed. Mueller's office was created specifically to investigate Russian meddling in the elections.
A section of the indictment against the Russians appears to refer to conduct by Pinedo.
"Defendants and their co-conspirators also used, without lawful authority, the social security numbers, home addresses, and birth dates of real U.S. persons to open accounts at PayPal, a digital payments company," the indictment against the Russians says.
On Friday afternoon, after being briefed about the indictment by Rosenstein, and after the release of the document, President Trump tweeted about the case.
White House spokeswoman Sarah Sanders soon after released a prepared statement from Trump in which he said, "It is more important than ever before to come together as Americans."
"We cannot allow those seeking to sow confusion, discord, and rancor to be successful. It's time we stop the outlandish partisan attacks, wild and false allegations, and far-fetched theories, which only serve to further the agendas of bad actors, like Russia, and do nothing to protect the principles of our institutions," Trump said. "We must unite as Americans to protect the integrity of our democracy and our elections."
While Trump and the White House on Friday were quick to claim that the indictment found no collusion by Trump's campaign with Russia, Bloomberg News reported that Mueller and his prosecutors have not concluded their investigation on that question.
Bloomberg cited an unidentified person with knowledge of Mueller's probe.
A spokesman for Clinton said she had no comment on the indictment.
The indictment said that the Internet Research Agency was registered with the Russian government as a corporate entity in 2013.
"By in or around May 2014, the organization's strategy included interfering with the 2016 U.S. presidential election, with the stated goal of "spread[ing] distrust towards the candidates and the political system in general," the indictment said.
House Speaker Paul Ryan, R-Wisc., said, "We have known that Russia meddled in the election, but these indictments detail the extent of the subterfuge."
"The Russians engaged in a sinister and systematic attack on our political system. It was a conspiracy to subvert the process, and take aim at democracy itself," Ryan said. "Today's announcement underscores why we need to follow the facts and work to protect the integrity of future elections."
