The United States has continuously claimed that Russian hacking affected the election. Tired of hearing this, Putin to Obama: put up or shut up.
Putin spokesman Dmitry Peskov said the United States should not "groundlessly" accuse the Russians of intervention in the United States election.
"They should either stop talking about that or produce some proof at last. Otherwise it all begins to look unseemly," Peskov said, according to reports.
On Thursday President Obama vowed retaliation against the Russians.
"I think there is no doubt that when any foreign government tries to impact the integrity of our elections that we need to take action and we will at a time and place of our own choosing," Obama told NPR.
Tension is rising as a result of the hacking. It now appears it is Obama's move in the back and forth between Vladimir Putin and President Obama.
