The Federal Bureau of Investigation is intensifying efforts to find enough evidence to enable the Justice Department to indict some of the Russians that U.S. intelligence agencies have concluded are hacking into American political parties and figures, U.S. law enforcement and intelligence officials said on Sept. 15.
Building legal cases is difficult, largely because the best evidence against foreign hackers is often highly classified, they said. Still, some White House and State Department officials think legal action is the best way to respond to what they said are growing Russian attempts to disrupt and discredit the November elections, without sparking an open confrontation with Russian President Vladimir Putin.
