The Sunday morning news shows were dominated by discussion about the Boston Marathon bombings, and the latest developments involving one of the suspects, who was taken into custody Friday.

While some Republican lawmakers have called for the surviving suspect, Dzhokhar Tsarnaev, to be held as an "enemy combatant," some Democratic lawmakers pushed back against the idea Sunday. Lawmakers also grappled with the question of whether and how the bombings should affect the immigration reform debate on Capitol Hill.
