 Ambassadors usually live in another nation.But the US ambassador to Syria isn't in Syria right now.He's back in the United States because of what the American officials have called credible threats against his personal safety.There're plans for him to go back to Syria at some point.No announcements about when that would happen.This is ambassador Robert Ford with president Obama.Ambassador Ford has been speaking out against Syrian government for using violence against protestors in the middle Eastern nations.Last month,the ambassador himself was attacked by a mob who supported the Syrian government.The US and Syria have a tense relationship right now.And that's in part because president Obama has called for Syrian president to leave power.President Obama is visiting Nevada,California and Colorado this week aimed at mixing presidential business with campaigning.He'll be talking about some of his plans designed to help the economy like his job bills that had been already rejected by the US Senate.The president will also go to campaign events.Remember he's running for re-election next year.And some critics,including the Republican presidential candidates,say the president is focusing more on getting re-elected than is on helping the country's economy.Nevada and California have high unemployment rates.So you can understand why the president might be there to talk about the economy.But Nevada and California are also swing states.That means experts say they could be important in next year's election.
