WASHINGTON (Reuters) - U.S. Republicans will push ahead with legislation reflecting their deep mistrust of a nuclear deal with Iran whatever the outcome of talks between Tehran and major powers in Switzerland, setting up further confrontation with President Barack Obama.
Just what action they will take - and how much support they get from Democrats - depends on the details agreed by negotiators from United States, Britain, France, Germany, Russia and China in Lausanne who are edging towards a preliminary deal due by the end of Tuesday.
