HONOLULU — In a sweeping response to election hacking and other bad behavior, President Barack Obama on Thursday sanctioned Russian intelligence services and their top officials, kicked out 35 Russian officials and shuttered two Russian-owned compounds in the U.S. It was the strongest action the Obama administration has taken to date to retaliate for a cyberattack."All Americans should be alarmed by Russia's actions," Obama said, adding, "Such activities have consequences."In a bid to expose Moscow's cyber aggression, the U.S. also released a detailed report about Russia's hacking infrastructure that it said was designed to help computer specialists identify compromised systems and prevent more hacking. And Obama said more action was coming."These actions are not the sum total of our response to Russia's aggressive activities," Obama said in a statement released while he was vacationing in Hawaii. The U.S. has previously left open the possibility it could mount a covert retaliatory strike.Russian President Vladimir Putin's spokesman Dmitry Peskov said Thursday that Moscow regrets the new U.S. sanctions and will consider retaliatory measures.The White House has promised to release a report before Obama leaves office detailing Russia's cyber interference in U.S. elections, a move that could address Russia's complaints that the U.S. hasn't shown proof of its involvement.
