House Republicans are exploring legal and constitutional strategies to block New York City mayoral-elect Zohran Mamdani from being sworn into office, citing the Constitution’s post–Civil War “insurrection clause.”

The effort, by the New York Post, is being led in part by the New York Young Republican Club, which argues that Mamdani’s past statements calling to “resist ICE” and his ties to left-wing organizations could qualify as “giving aid or comfort to the enemies” of the United States — language drawn directly from Section 3 of the 14th Amendment.

That provision, enacted in 1868, bars from public office any person who has “engaged in insurrection or rebellion” against the United States, or who has provided “aid or comfort” to its enemies.

The clause was originally intended to prevent former Confederate officials from holding office but has recently re-emerged in political debates over ballot eligibility.
