Two cases argued at the U.S. Supreme Court on Monday could have major ramifications for immigrants in this country and public sector unions.

First, the Supreme Court refused to hear an appeal by the Trump administration to end DACA, which makes the March 5 deadline to shut down the program invalid.

Secondly, the court heard the case Janus v. American Federation of State, County, and Municipal Employees, Council 31, which centers around the requirement for government employees covered under a union contract to pay union fees even when they are not members.

Philip Bump, national correspondent for the Washington Post, brings his analysis to both cases.
