How do you know when a politician is lying? When his lips are moving:

A US senator on Wednesday said Russian internet trolls were stoking the NFL debate to try and stir up divisiveness in America.

Hundreds of sports stars have taken the knee in protest since President Trump declared on Friday that NFL players who refused to stand during the national anthem were ‘sons of b***hes’ and should be fired.

Since then, the hashtags #TakeAKnee and #BoycottNFL have been trending and the movement has been picked up by celebrities, scientists and doctors who have shared pictures of them kneeling in solidarity on social media.

On Wednesday, Sen. James Lankford, of Oklahoma, claimed that Russia had paid social media trolls to stoke the debate in an attempt to polarize America. He said they have been sharing the hashtags ‘take a knee’ and ‘boycott NFL’ to amplify the issue and spread discord.

‘We watched, even this weekend, the Russians and their troll farms, their internet folks, start hashtagging out #TakeAKnee and also hashtagging out #BoycottNFL,’ Lankford, who sits on the Senate Intelligence Committee, said during a hearing on threats faced by the United States.
