other storm in washington, over the automatic spending cuts set to kick in on friday. 85 billion. Today, president obama met informally with the leaders of both parties in congress. It was brief, just a few minutes. They are scheduled to talk again friday, but there is no sign of any deal to avoid the blunt force of the cuts. Even though today, in an exclusive interview, the attorney general told our senior justice correspondent pierre thomas the sequester cuts will hurt national security. Reporter: After a top secret fbi briefing on the nation's terror threat this morning, the attorney general issued a stark warning about those deep budget cuts. There are not going to be as many fbi agents, atf agents, dea agents, prosecutors doing their jobs. They're going to be furloughs. Reporter: You have members of the republican party saying that it's smoke and mirrors, that the administration is crying wolf. That it's fear mongering. This is something that is going to have an impact on the safety of this country. Anybody that says that's not true is either lying or saying something that runs contrary to the facts. Reporter: As we spent the day with him, it was quite clear that many explosive issues were engulfing his department. On capitol hill, a dramatic hearing about the newtown massacre, a reminder of the epic political battle over gun control. Jesse was the love of my life. He was the only family I had left. It's hard for me to be here today to talk about my deceased son. I have to. I'm his voice. Reporter: Holder said the day he went to newtown marked him for life. I have to tell you that walking through sandy hook elementary school and going into those classrooms and seeing the caked blood, seeing the crime scene photos of these little ajells was the most difficult thing that I have ever had to do in my professional life. Reporter: Were you fighting back tears, may I ask? Unsuccessfully. I tried to hold it together as best I could. Reporter: Holder said he has ordered his staff to study ways to identify mass shooters before they strike, and he vowed to fight for the assault weapons ban. He tells me he believes its will pass. I think what we as a nation have said is enough is enough. Reporter: We'll see if that's true in the coming months. Pierre thomas, abc news, washingt.
