Trump, Macron face differences on Iran, trade, in French visit

US President Donald Trump welcomes France's Emmanuel Macron to the White House on Monday at the start of a three-day state visit expected to be dominated by US-European differences on the Iran nuclear deal and souring trade relations.

It will be Trump's first hosting of a state visit since he took power in January 2017.

The pair will get a sense of their two countries' shared history during an evening meal on Monday night at Mount Vernon, the home of George Washington, the first US president and Revolutionary War commander whose alliance with France was critical to victory over the British.
