( CNN) The Senate Intelligence Committee's leaders said Wednesday they believed that the intelligence community's 2017 assessment of election meddling was correct, breaking with Republicans on the House Intelligence Committee who questioned the conclusion that the Russians were trying to help President Donald Trump get elected.

The top Democrat on the committee, Sen. Mark Warner of Virginia, was of the view that “after a thorough review, our staff concluded that the ICA conclusions were accurate and on phase. The Russian effort was extensive, sophisticated and ordered by President Putin himself for the purpose of helping Donald Trump and hurting Hilary Clinton.”

The joint statement comes after former director of the National Security Agency Michael Rogers, former CIA Director John Brennan and former Director of National Intelligence James Clapper sat down with the committee in a closed hearing Wednesday morning about the 2017 assessment.
