President Donald Trump insisted Friday that his campaign did not collude with Russian operatives in 2016.

"Russia started their anti-US campaign in 2014, long before I announced that I would run for President. The results of the election were not impacted. The Trump campaign did nothing wrong - no collusion!" he tweeted.

The remarks came shortly after Rod Rosenstein announced indictments against 13 Russian individuals and three Russian entities in special counsel Robert Mueller's probe.

The indictments allege the Russian operatives were intent on meddling "with U.S. elections and political processes." That meddling included "supporting the presidential campaign of then-candidate Donald J. Trump and disparaging Hillary Clinton."

Rosenstein said the operation used "Russian shell companies."

"It employed hundreds of persons for its online operations, ranging from creators of fictitious personas to technical and administrative support, with an annual budget of millions of dollars," he explained.
