"This aggressiveness was evident in Russia's efforts to influence the 2016 USA election and we assess that only Russia's senior-most officials could have authorized the 2016 USA election-focused data thefts and disclosures, based on the scope and sensitivity of the targets", Coats wrote in his statement.
The remarks from Director of National Intelligence Dan Coats come as the Trump administration conducts a comprehensive review of its Iran policy. He says such activity has diminished since U.S. Coats declined to provide such details in an open hearing.
Coats said China was also targeting the United States government and American businesses.
The Director of the Central Intelligence Agency, Mike Pompeo, warned that North Korean risks still remain and the threat is very real.
Testifying beside Coats, the head of the military's Defense Intelligence Agency, Vincent Stewart, said the state of the 15-year conflict will deteriorate from a stalemate in favor of the belligerents if left unchecked.
"It's clear that we have assessed this as a very significant, potentially existential threat to the United States that has to be addressed".
The report also notes that Iran's progress in its space program could expedite its path to an ICBM since space launch vehicles use similar technologies.
The Trump administration is considering sending 3,000 to 5,000 additional troops to Afghanistan to help train Afghan security forces.

The five-judge bench headed by J S Khehar comprised of Justices Kurian Joseph, U U Lalit, Abdul Nazeer, and R F Nariman. The apex court had earlier even asked the Chief Justice of the Madras High Court not to assign him any judicial work.
Coats described the growing threat of Iran's missile program in a written testimony to the Senate Select Committee on Intelligence on Thursday.
North Korea's missile tests in 2016, including a space launch that put a satellite into orbit, have shortened its pathway toward a reliable intercontinental missile that could strike the USA, he said, and the North has expanded the size and sophistication of its ballistic missile forces.
The amount of time it would take for Iran to produce enough fissile material for a nuclear weapon is estimated to be from a few months to a year.
But he said the USA doesn't know if Iran will eventually decide to try to build nuclear weapons.
The nuclear program of the Democratic People's Republic of Korea (DPRK) posed a "potentially existential threat" to the United States, U.S. National Intelligence Director Dan Coats said on Thursday.
Coats testimony was part of a list that included the interim Federal Bureau of Investigation director, Andrew McCabe, who spoke in lieu of his fired former boss, James Comey. The performance of Afghan national security forces will worsen because of weak military leadership, desertions and combat casualties, he predicted.
Sunni extremists remain the primary terrorist threat to the US, with home-grown actors posing the biggest concern.
