US SENATOR Larry Craig says he is reconsidering his decision to resign after his arrest in a Minnesota airport sex sting and may still fight for his senate seat, his spokesman said.

A British man accused of travelling to the US to have sex with children told authorities that he had changed his mind, and instead he flew to Minnesota to talk his fiancee out of their plan to molest young girls.

The lawyer of a British man accused of flying to Minnesota to have sex with children argued in court today that evidence against him should be suppressed.
