Washington (CNN) Only President Donald Trump can possibly think he's a "very good messenger" to exploit Joe Biden's controversy over complaints that his tactile political style made some women uncomfortable.

Yet Trump, who has faced far more serious allegations about his own behavior, made just that argument on Friday, showing how he just ignores charges of hypocrisy that would make a normal politician avoid such sensitive ground.

"I think I'm a very good messenger, and people got a kick out of it," Trump told reporters at the White House.

"He's going through a situation, let's see what happens. But people got a kick ... we gotta sort of smile a little bit, right?" Trump said, adding that he doesn't see the former vice president as a threat in the 2020 election.

Trump's willingness to tackle Biden's problems head on is not just an example of the remarkable chutzpah that underpins his unorthodox political method. It is a fresh indication of how the President has warped expectations that would exact a heavy price from a conventional candidate for similar behavior.
