The lower house of Russia’s parliament on Wednesday approved the critical second reading of a proposed law that would allow the banning of foreign news media in response to other countries taking actions against Russian news outlets. The proposal must still pass a third reading in the Duma and secure the upper house’s approval before going to President Vladimir Putin to be signed into law. But the Duma’s approval on second reading, when a proposal still can undergo substantial changes, almost always prefigures a law’s enactment.
