The lawyer who is coordinating WikiLeaks founder Julian Assange's legal defense against extradition to Sweden says he will ask U.S. authorities whether his client also is under investigation there.
Former Spanish Judge Baltasar Garzon said Wednesday he will send a petition to the U.S. prosecutors asking them that.
Assange, who is seeking to avoid extradition to Sweden for questioning over sex crimes allegations, has been sheltering inside Ecuador's Embassy in London -- beyond the reach of British police -- since June 19.
He claims the Swedish sex case is merely the opening gambit in a plot to make him stand trial in the United States over his work with WikiLeaks, which has published large troves of secret U.S. documents.
Sweden and Washington reject those claims.
