More than four years after Dzhokhar Tsarnaev was sentenced to death for his role in the Boston Marathon bombings, his attorneys asked a judge Thursday to throw out his conviction. The defense argued to a federal appeals court that Tsarnaev's right to a fair trial was violated when the judge refused to move proceedings out of Boston, pointing to two jurors who, they argue, demonstrated bias against the defendant in social media posts.

To discuss, Jim Braude was joined by Brian Kelly, a former assistant U.S. attorney and a partner at Nixon Peabody, and Renee Landers, Suffolk University professor and constitutional law expert.
