The Justice Department wants to reinstate the death sentence for the convicted Boston Marathon bomber.
The DOJ is asking the Supreme Court to review a federal appeals court's decision to vacate the sentence last month. The appeals court ruled the judge didn't properly screen jurors for potential biases.
That ruling means the bomber could get a new penalty phase trial — with a new set of jurors to decide if he should be sentenced to death.
Three people were killed and more than 260 others were hurt in the 2013 bombing.
