President Vladimir Putin has commented publicly for the first time on U.S. Special Counsel Robert Mueller’s investigation into Russia’s alleged collusion with President Donald Trump’s campaign.

Russia has repeatedly denied claims that it interfered in the 2016 U.S. presidential election, although U.S. intelligence agencies concluded that it did. Last month, Mueller’s nearly two-year investigation concluded that there was no evidence of collusion between Russia and the Trump campaign, according to a summary of its findings.
