The Senate Intelligence Committee confirmed on Wednesday that it has “been rigorously tracking this issue from the start” and is “discussing an appropriate response with the administration,” per a note from Virginia Sen. Mark Warner, the committee’s chair, and Florida Sen. Marco Rubio, the committee’s vice chair. The Senate is currently on a two-week recess. “In the meantime, we must be cautious about potentially disclosing sources and methods that may be key to preserving a range of options for U.S. action.”
