TEHRAN, Iran – US President Donald Trump said Monday that talks with Iran were moving at a “rapid pace”, even as Tehran threatened to widen the war by keeping the Strait of Hormuz blocked and activating other pressure points around the region.

WASHINGTON (AP) — Secretary of State Marco Rubio said Tuesday that he is optimistic about the potential for a resumption in nuclear talks with Iran despite a shaky ceasefire in the war that is looking increasingly in doubt.

Secretary of State Marco Rubio will testify before the Senate Tuesday morning in his first public testimony since the war with Iran began.

Secretary of State Marco Rubio said Tuesday that any new nuclear deal with Iran would have to go far beyond the Obama-era JCPOA, arguing that agreement failed to stop Tehran from building up its enrichment capabilities.

The deal could extend a U.S.-Iran ceasefire and open the Strait of Hormuz. CBS News New York's Wendy Gillette reports.
