Senator Molan has defended his decision to re-post videos from Britain First last year but says he has since "given up" on using Facebook.
Newly sworn-in Liberal senator and former military general Jim Molan has condemned the anti-immigration group Britain First as an "appalling organisation", but maintains he did nothing wrong by sharing some of their videos on Facebook.
Senator Molan, who recently occupied the Upper House seat vacated by Fiona Nash, shared the videos on his Facebook account in March last year.
Fairfax Media uncovered the videos and reported them on Monday. One is titled 'Muslim Thugs Beat Girl in Holland', while a second claims to show Muslim men attacking French police cars.
Opposition leader Bill Shorten condemned the sharing of the videos.
"I think it was probably unwise to share these videos, they are repugnant," Mr Shorten told reporters at Parliament House on Tuesday.
Greens senator Nick McKim tweeted Senator Molan was "a blatant racist who brags about the cruelty of offshore detention, and revels in trampling rights and freedoms".
