He told his radio audience that he was intending to sue British Home Secretary Jacqui Smith, who he described as the "lunatic ... Home Secretary of England".
"To link me up with skinheads who are killing people in Russia, to put me in league with Hamas murderers who kill people on buses is defamation," he said.
In an article posted on his website, he said he did not advocate violence but "traditional values".
He wrote: "What does that say about the government of England? It says more about them than it says about me."
Lawyers say it would be difficult for Mr Weiner to bring an action for defamation given that the list was issued with the authority of the British government.
They note that English law recognises that there are cases when there is a legitimate and public interest in information being made widely available, and that unless the government acted out of improper motives for placing him on the list, any libel claim is unlikely to get very far.
Mr Weiner has offended many in the US with his views on immigration, Islam and rape.
He also angered the parents of children with autism by saying most cases were "a brat who hasn't been told to cut the act out", the Associated Press reported.
