5. No info to Apple: A  federal law enforcement officer said Monday that the FBI is not likely to tell Apple how they hacked into an iPhone carried  by Syed Farook when he shot and killed 14 in San Bernardino in December. According to government policy, if a software vulnerability is discovered in a product, then a government review is triggered and the agency must tell the company how it was able to hack into the product. In this case, the FBI said it had not positively identified the issue, so it won't be talking to Apple about how they hacked into the iPhone. The FBI paid an outside party more than $1.3 million to break into Farook's phone.

And  one more

Twitter was buzzing Tuesday night over the reaction of New Jersey first lady Mary Pat Christie to a statement about Hillary Clinton that Donald Trump made during his victory speech.. Christie appeared to roll her eyes as she glanced at her  husband, former GOP candidate for the nomination and Trump supporter,  Chris Christie. The reaction came when Trump said, "The only card she (Clinton) has is the woman's card. She's got nothing else going on. And frankly, if Hillary Clinton were a man, I don't think she'd get 5 percent of the vote. The only thing she's got going is the women's vote. And the beautiful thing is that women don't like her."
