UPDATE: President Obama sounds very sure this is a serious, Iranian-government directed plot:
In his first public remarks on the issue since it was revealed on Tuesday, Mr. Obama sought to counter skepticism about whether Iran's Islamic government directed an Iranian-American car salesman to engage with a Mexican drug cartel to assassinate Saudi Arabia's ambassador to the United States and carry out other attacks. Mr. Obama insisted that American officials "know that he had direct links, was paid by, and directed by individuals in the Iranian government."
"Now those facts are there for all to see," Mr. Obama said. "We would not be bringing forward a case unless we knew exactly how to support all the allegations that are contained in the indictment."
