Ben Shapiro has slammed Twitter for saying Rosie O'Donnell was not abusive when she 'harassed' him on the social media platform.

The conservative columnist and commentator reported the former The View host after she directed a vulgar comment at him.

O'Donnell told editor in chief of the Daily Wire Shapiro to 'suck my d*** ben' in a tweet that she later deleted.

She then taunted him for looking like a 'high school junior' when he said the remark was sexual harassment.

Shapiro wrote in a tweet on Friday:  'Just reported @Rosie for targeted harassment, mainly to see if Twitter does indeed have a double standard. Everyone knows if Rosie were conservative, Twitter would suspend her in a hot second. So, Twitter, put your money where your mouth is.'

He then wrote: 'It's an attempt to clarify Twitter's standards. I don't actually want them to ban or suspend Rosie. I want them to stop applying their own rules inconsistently.'

Just a few hours later, Shapiro revealed to his followers that he had already got a response from Twitter.

Alongside a screenshot of the decision from Twitter, he wrote: 'Surprise of surprises. Twitter says that @Rosie's tweets were not in fact abusive in any way under their rules. Good to know.' 

The feud between the pair started when Shapiro slammed the talk show host for saying she would give Senators Susan Collins and Jeff Flake $2million for voting against the Republican's tax reform.

Many critics, including Shapiro, said the payment would be a violation of federal law. 

After Shapiro alerted his followers that he had reported O'Donnell, she simply replied, 'oh ben'.

He responded to her by saying: 'All victims deserve to be believed.'
