Ian Bremmer shares his insights on global politics this week on World In :60.

If the US won't work to return a wrongly deported man to El Salvador despite a Supreme Court ruling, are we headed towards a constitutional crisis?

It certainly appears that way, and I think this is the constitutional crisis that the Trump administration would love to have. Because wrongfully deporting someone without evidence who is in the country illegally and therefore guilty of a misdemeanor, but sending them to a max security prison, which the Supreme Court says you shouldn't do, but now is in another country. Very few Americans are sympathetic to the case of this person. And indeed, Trump won on the basis in part of being sick and tired of allowing illegal immigrants to spend enormous amounts of time in the United States without recourse.
