The justices agreed to hear an appeal filed by the Trump administration, which carried out executions of 13 federal inmates in its final six months in office, including three in the last week of President Donald Trump’s term. The case won’t be heard until the fall, and it’s unclear how the new administration will approach Tsarnaev’s case. The initial prosecution and decision to seek a death sentence was made by the Obama administration.... Biden has pledged to seek an end to the federal death penalty, but he has said nothing about how he plans to do so.... In late July, the federal appeals court in Boston threw out Tsarnaev’s sentence because, it said, the judge at his trial did not do enough to ensure the jury would not be biased against him. The Justice Department had moved quickly to appeal, asking the justices to hear and decide the case by the end of the court’s current term, in early summer. Then-Attorney General William Barr said last year, 'We will do whatever’s necessary.'"
