Deport DSA supporters who are naturalized citizens

When a person becomes a naturalized citizen, they take an oath to defend and support the constitution of the US. The DSA platform wants to do away with the presidency & the senate and defund the Dept. of War.
Mandami, Ilan Omar are naturalized, and there are others that I can't be sure of, but the State Dept. should revoke their citizenship & deport them, because if they advocate the DSA, they are advocating doing away with our constitution as it was written.
