Russia responded Thursday to U.S. and other nations' reaction to the poisoning of former double agent Sergei Skripal in England. Russia expelled 150 diplomats from the country, including 60 Americans. The U.S. recently ordered 60 Russians out of the country. Russia will also close the U.S. consulate in St. Petersburg after the U.S. shut down the Russian embassy in Seattle earlier this month. CBS News state department reporter Kylie Atwood discusses the latest developments.
