Russian state media have reported Thursday that U.S. Secretary of State Marco Rubio may attend Moscow's May 9 celebrations in Red Square to commemorate the end of World War Two. Zvezda, a TV channel of the Russian defense ministry, cited an unnamed diplomatic source that the U.S. might be represented by Rubio at the show piece event for the Kremlin which parades Russian military hardware. Newsweek has contacted the U.S. State Department and the Kremlin for a response.
