NSW Labor MLC Shaoquett Moselmane says his decision to link Twitter followers to a story on the website of a former Ku Klux Klan leader was "a bad mistake".
The tweet, which he posted about 10:00pm last night and subsequently deleted, directed people to the homepage of American white supremacist David Duke.
Mr Duke is a former Ku Klux Klan grand wizard and state politician in Louisiana.
The story was titled: Israel Lobby Controls Australian Foreign Policy — Former Foreign Minister Bob Carr.
Mr Moselmane, who was elected in 2009, is the first Muslim MP in NSW.
