President Obama speaks out on the IRS scandal is the acting commissioner resign; the White House releases more than hundred pages of e-mails related to the aftermath of the Benghazi attack.

First interview with a dance instructor lost her leg after the Boston bombing one month ago. Let's get start.

Tonight with the breaking news on 2 fronts: the IRS scandal; and the response to the Bengahzi attack left 4 Americans dead. Just a short time ago, president Obama spoke out on the IRS scandal over charges that it singled out the conservative groups and targeted them for extra scrutiny. The president announced that the acting commissioner of the IRS was fired, and president promised that his administration will work with Congress to make sure nothing like this happens again. Listen--I've reviewed the Treasury Department watchdog's report and the misconduct that in cover is inexcusable. It's inexcusable, and Americans are right to be angery about it, and I am angery about it. I would not tolerate this kind of behaviour in any agency, but especially in the IRS, given the power that it has and the rich that it has in all our lives. And as I said earlier, it should not matter what political stripes you're from, the fact of the matter is that the IRS has to operate with absolute integrity. The government generally has to conducts itself in a way that is true to the public trust, that's especially true for the IRS.

Also today, the White House releases more than a hundred pages of e-mail correspondence showing how officials came up with response to the Bengahzi attack. The administration response. The e-mails are between the White House, the FBI, the CIA, the state deparment and other agency, showing how the so-called talking points change over time as officials worked on what to tell the Congress and American people about the attack.

275 people were injured here one month ago. Tonight, 6 are still hospitalized. And we think of them tonight.

More than a dozen bombing survivers lost limbs. Among them, Adrianne Haslet Davis, the 32-year-old dance instructor. She lost her left foot in the second explosion. Her left leg had been amputated below the knee. After the bombings I talked to Adrianne in the hospital. She's one of those people you can't forget her spirit and determination on &&&.She determined to dance again. I've no doubt she will.

A lot people here around the country rooting for Adianne and all the other injured. The co-workers, the Alzmera dance studio, set up a fund to raise money for her expenses. If you'd like to make contribution, go to fundme.com/Adrianne fund. We're excited about following Adriane a month ahead. I sat down with her again today. First time we see each other since the week after the bombings.
