ALEXANDRA FIELD, CNN CORRESPONDENT (voice-over): Dzhokhar Tsarnaev, impassive in the courtroom, showing no emotion, while the government makes its final appeal to hold him accountable, soon asking jurors to consider the death penalty.</s>FIELD: The defense made their closing statements just following the prosecution. In it, they said that Dzhokhar is ready to accept responsibility, but, Jake, they continue to underscore the point that they have been making throughout this trial, saying that none of what did happen would have happened if it had not been for Tamerlan. They argue this theory. Their defense is that Dzhokhar was coerced by his older brother, Tamerlan. And, Jake, we will see what kind of impact that really has in the verdict phase of this trial. It could have a big impact, however, in the sentencing phase of this trial, when jurors would be asked to consider the death penalty -- Jake.</s>TAPPER: Alexandra Field live in Boston, thank you so much for that report. In our politics lead: She's expected to formally announce her candidacy any day, but even without an official declaration, Hillary Clinton's campaign is quickly taking shape, though two of her potential Democratic rivals are already out there trying to sway voters before she jumps in. That's next.
