Trump "has been fully briefed on this matter and is glad to see the special counsel’s investigation further indicates—that there was NO COLLUSION between the Trump campaign and Russia and that the outcome of the election was not changed or affected," White House press secretary Sarah Huckabee Sanders reiterated in a statement.

Federal investigators have not reached a conclusion about whether Russian meddling impacted the result of the election.

"There is no allegation in the indictment on the outcome of the election," Rosenstein noted Friday in the announcement.

The White House has not always acknowledged that the ongoing investigation into Russian interference in the 2016 election is legitimate. Trump has previously referred to the probe, which expanded last year to include scrutiny of his campaign's alleged involvement, as a "witch hunt" and "hoax."

The indictment notes the Russians’ efforts to influence the U.S. election began in 2014 and were connected to the Internet Research Agency, a Russian operation based in St. Petersburg that used social networks to spread divisive messages in the lead up to the 2016 election.

“The indictment alleges that the Russian conspirators want to promote discord in the United States and undermine public confidence in democracy,” Rosenstein said.

In a similar statement released by the White House, Trump said it is time "to come together as Americans."

"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.”

It also says that some of the Russians posed as U.S. people and communicated with “unwitting individuals associated with the Trump Campaign and with other political activists to seek to coordinate political activities.”

Rosenstein noted that there is no allegation in the indictment that Americans had any knowledge of the operation.
