President Trump has commented on Joe Biden’s habit of hanging his face mask on one ear.

During a rally at an airport in Pennsylvania, Trump said: “I’ve never seen a man that liked a mask so much”

Breitbart reports: Trump said he was “all for” Americans wearing masks to help stop the spread of the virus, urging Americans to keep washing their hands and remain socially distanced over the Labor Day weekend.

But he mocked Biden for his mask-signaling behavior.

“Did you ever see a man who likes a mask as much as him?” Trump asked, noting that sometimes Biden even hung his mask over his ear when he was speaking.

“It gives him a feeling of security,” Trump continued. “If I were a psychiatrist, right? You know, I’d say, ‘This guy’s got some big issues.”

Earlier in the campaign, Biden would speak at length with a mask dangling from his ear.
