Twitter said on Thursday that it's immediately removing all off-board advertising from two of Russia's largest media outlets, Russia Today and Sputnik.

In late September, Twitter said that three accounts tied to Russia Today, including @RT_Com, @RT_America and @ActualidadRT, were specifically targeting "the U.S. market in 2016" ahead of the Presidential election. Twitter said at the time that RT spent $274,000 in U.S. ads last year and promoted more than 1,823 tweets.
