US Republicans move toward Iran deal showdown with White House

WASHINGTON - Legislation that could undermine the international nuclear deal with Iran cleared a US congressional panel on Thursday, setting up a potential showdown over one of President Barack Obama's signature foreign policy initiatives.
The Republican-led Foreign Affairs Committee of the House of Representatives approved the measure by a voice vote that appeared to be along party lines, setting it up for consideration by the full House.
Opponents say the "Iran Terror Finance Transparency Act," which would increase lawmakers' oversight of the Iran agreement announced in July, is an attempt by Republicans to violate terms of the landmark deal with new legislation because they could not muster enough opposition to scuttle it last year.
