WHITFIELD: All right, we're following new developments out of Syria where the terror group ISIS appears to have declared a state of emergency. The Pentagon says it's seeing new evidence of ISIS fighters being scrambled inside its self-declared capital of Raqqa, possibly preparing for a siege. This comes after U.S.-backed forces have started to surround the city in recent months helping cut off supply lines. CNN Pentagon Correspondent Barbara Starr explains.</s>BARBARA STARR, CNN PENTAGON CORRESPONDENT: U.S. military officials have been closely monitoring social media and other reports that ISIS has declared a state of emergency in Raqqa, its self-declared capital inside Syria, that's a city that ISIS holds very dear. They've been in control of it for some time. So what is this state of emergency really mean? U.S. officials saying they have some evidence showing ISIS fighters are moving around in the city, some of them trying to leave the city, that they're putting up cover, shades, trying to cover sidewalks, areas where they may be, all to try and stay hidden from potential air strikes or ground action. ISIS may, in fact, be getting nervous in Raqqa. They have seen militia movements move closer and closer, some of the areas surrounding Raqqa now not necessarily under ISIS control. All of this making the group, maybe for the first time, very nervous about being able to hold on to the city that they consider their capital.

"It's none of your business," that is what Donald Trump is telling critics who are demanding a release of his tax returns. Will this hinder his chances in November or help? That's next.
