A company responsible for Russian government-backed media in the United States has registered as a foreign agent, the Justice Department announced Monday.

The registration brands RT America’s broadcasts as the product of a foreign government. The move follows months of wrangling between RT, formerly known a Russia Today, and the Justice Department. Federal officials overlooked the media outlet’s Kremlin ties in recent years, in part to avoid retaliation against American media in Russia, but that changed after U.S. intelligence agencies identified RT as an important player in the 2016 election interference.
