Thane Rosenbaum, CBS News legal analyst, on the Supreme Court's birthright citizenship arguments

Thane Rosenbaum, CBS News legal analyst, joins Tony to break down the historic Supreme Court arguments over birthright citizenship and the 14th Amendment, including the significance of President Trump attending the session in person. Rosenbaum explains the key legal questions raised by the 1898 case at the center of the arguments, what the justices' questions may signal about their leanings, and why he believes at least seven justices are likely to rule against the executive order and in favor of birthright citizenship.
