"When we finish with Trump, we have to go and get Putin, he's next," the congresswoman said.
"Putin or Pence?" Behar asked.
"Ah, Pence," Waters corrected herself.
"We get two for one: Trump and Putin, and then we got to go after Pence," Behar said in order to smooth the awkwardness caused by Waters' mistake.
The US politician had already made controversial statements before. Earlier she said that Trump and Russian leader Vladimir Putin are "tied at the hip."
She also claimed that Russian President "Putin is continuing to advance into Korea."
After her statement, Russian phone pranksters known as Vladimir Kuznetsov (Vovan) and Alexei Stolyarov (Lexus) decided to make fun of her.
By introducing himself as "Volodymyr Groysman, prime minister of Ukraine," one of the pranksters informed the clueless congresswoman that President Putin invaded an African "country" called Limpopo, which actually doesn't exist. Waters perceived the joke seriously and promised to investigate the issue.
