White House coronavirus adviser Scott Atlas apologized on Sunday for giving an interview to Russia's Kremlin-backed television station RT, saying he was unaware the outlet was a registered foreign agent in the United States. Atlas, a neuroradiologist and member of the White House coronavirus task force, appeared on the channel on Saturday and criticized coronavirus lockdowns measures, calling them an "epic failure" at stopping the virus' spread. "I recently did an interview with RT and was unaware they are a registered foreign agent," Atlas wrote on Twitter.
