Fidel Castro was not interested in personal enrichment. His supporters say he deployed his enormous authority on behalf of health, education and welfare programs that brought Cuba attention around the world.

Holocaust Museum said ISIS has carried out genocide against the Yazidis, but its investigation did not cover Christian persecution. Now there's concern the U.S. State Department might do the same, limiting any genocide pronouncement to Yazidis without mentioning Christians.

Hispanics are the fastest-growing evangelical group in the country right now, an important constituency. But Trump's views, especially his views on immigration, did not exactly go over well with this faith constituency. Rev. Rodriguez told me that Trump's invitation created something of a stir in his world.

Fidel Castro outlasted U.S. presidents determined to overthrow him, survived the collapse of the communist bloc that sustained him and outlived many of those who wanted to replace him. For those reasons, he will go down in history as among the world's most skillful politicians, even if his achievements largely die with him.

There's a culture war in this country. Americans in recent years, as you know, have become more secular. They don't go to church as often. Bible reading, prayers in public are now frowned upon. And, of course, in addition to that, a lot of people have become much more supportive of LGBT rights. And in reaction to that, biblically conservative Americans feel that their faith is under assault.

ISIS goes after any group that deviates from its extreme ideology, dissident Muslims, for example, or the Yazidis who practice an ancient religion distinct from both Islam and Christianity.

Donald Trump seems to prefer people he sees as being on his side.
