Sens. Johnson, Grassley accuse Democrats of 'disinformation' about their foreign interference probe

Top Senate Republicans Ron Johnson and Chuck Grassley on Tuesday accused chamber Democrats of leaking information and spreading disinformation in an effort to discredit their investigation into national security and foreign election interference.

Johnson, chairman of the Senate Homeland Security and Governmental Affairs Committee, and Grassley, chairman of the Senate Finance Committee, made their argument in letter to the top Democrats on their respective committees.

The senators say their letter is a response to a Democrats' letter earlier this month requesting a briefing from the FBI and other members of the U.S. intelligence community.

Congressional Republicans argue that the agencies have made clear that they have no more information to share. 

"Finally, we want to reiterate that we have taken every precaution to protect the integrity of our investigation and keep your staffs involved in our work," Johnson and Grassley wrote. "Yet at every turn, we have seen leaks of sensitive information and attempts to smear and undermine our investigation – and us, personally – in the press. These attempts to discredit our investigation only serve to increase our curiosity: what are the Democrats and many in the media so afraid of us finding?"
