The Russian president faces a backlash after suggesting minority groups, including Jews, may be responsible for meddling in the 2016 US election.
Vladimir Putin made the comments during a US TV interview with Megyn Kelly. US lawmakers and Jewish groups are among those criticising him.
Some are publicly asking US President Donald Trump to push Mr Putin for a clarification on what he meant when questioning whether certain groups were actually Russian.
Mr Putin was being asked during the NBC interview about charges of alleged Russian meddling in the 2016 election after 13 nationals were charged by the US special counsel’s office last month.
“I couldn’t care less because they do not represent the government, I could not care less. They do not represent the interests of the Russian state,” Mr Putin said.
“Maybe they’re not even Russians, but Ukrainians, Tatars, Jews, just with Russian citizenship. Even that needs to be checked.
“Maybe they have dual citizenship. Or maybe a green card. Maybe it was the Americans who paid them for this work. How do you know? I don’t know.”
