When Obama instituted his first of six travel bans in 2011, he cited the same legal justification as his predecessors: the Immigration and Nationality Act of 1952. Section 212(f) of that law states: “Whenever the president finds that the entry of aliens or of any class of aliens into the United States would be detrimental to the interests of the United States, the president may, by proclamation, and for such period as he shall deem necessary, suspend the entry of all aliens or any class of aliens as immigrants or non-immigrants or impose on the entry of aliens any restrictions he may deem to be appropriate.”

Factions of our judicial branch have gone out of their way to override our chief executive based on partisan politics, not precedent. The battle over the proposed travel ban isn’t about unscreened travel from Muslim-majority nations; it’s about liberal activist judges and their partisan agenda for America’s national security policy.
