"The European Union and its Member States express their solidarity with the United States on the impact of malicious cyber activities, notably the SolarWinds cyber operation, which, the United States assesses, has been conducted by the Russian Federation," foreign policy chief Josep Borrell said in a statement. del/rmb/kjl
