Craig Kelly’s support of convicted child molester Cardinal George Pell has pushed a “disgusted” Liberal colleague to condemn the MP, two months since the Prime Minister blocked anyone from challenging Mr Kelly for his seat.

Kent Johns, the former NSW Liberal Party President and current Vice President, said Mr Kelly’s comments caused “hurt” to victims and he “should know better.”

In a Facebook post, Craig Kelly questioned Cardinal Pell’s conviction on child sex abuse charges, saying it seems to be a “grave miscarriage of justice”.

The Member for Hughes then inserted Bolt’s column into the rest of his Facebook post, in which the News Corp commentator claimed Pell had been “falsely convicted of sexually abusing two boys in their early teens”.

“The problem with his (Kelly’s) comment is that he is our representative in the Federal Parliament so he is supposed to speak for our community,” Kent Johns said.

“This case has victims of abuse reliving their trauma and this just causes more pain by questioning the justice system. It may make victims even more unlikely to come forward because they feel they won’t be believed. ”

Mr Johns pointed to previous social media posts from Mr Kelly, where he likened school students protesting climate change to child abuse.

“(Kelly’s) comments hurt not only those involved but many people in my community who have suffered and he should know better than that.” Mr Johns said.

“It makes them question who is there to stand up for them, if their own parliamentarian doubts the justice system.”

Kent Johns had the overwhelming support of local Liberal party members to defeat Craig Kelly in preselection in the south west Sydney seat of Hughes.

In December, Prime Minister Scott Morrison and his supporters directed NSW Liberal Party State Executive to agree to a special ballot which endorsed all sitting members.

The move stopped any outstanding preselection and allowed Mr Kelly to recontest the May byelection without facing a vote of his local party members.
