Arizona Sheriff Joe Arpaio of Maricopa County sued Barack Obama over his unconstitutional executive amnesty today.
Sheriff Joe filed the suit in US District Court for the District of Columbia.
Freedom Watch reported:

(Washington, D.C., November 20, 2014) Today, in response to the executive order President Barack Obama has signed effectively granting amnesty to about a half of the illegal aliens currently in this country, Sheriff Joe Arpaio of Maricopa County, Arizona filed a lawsuit to enjoin this unconstitutional act. This lawsuit can be found at www.freedomwatchusa.org.

Sheriff Arpaio’s lawyer is Larry Klayman of Freedom Watch, former federal prosecutor and founder of both Judicial Watch and Freedom Watch. Mr. Klayman recently succeeded in obtaining a preliminary injunction against the National Security Agency for having unconstitutionally accessed the telephonic metadata of nearly all American citizens. See Klayman v. Obama, et al (Civil Action No. 13-cv-851), filed in the U.S. District Court for the District of Columbia.

Upon filing the complaint, which is styled Arpaio v. Obama, et al. before the U.S. District Court for the District of Columbia (Civil Action No. 14-cv-1966), Sheriff Arpaio issued this statement:

“This unconstitutional act by the President will have a serious detrimental impact on my caring out the duties and responsibilities for which I am encharged as Sheriff. Specifically, it will severely strain our resources, both in manpower and financially, necessary to protect the citizens I was elected to serve. For instance, among the many negative affects of this executive order, will be the increased release of criminal aliens back onto streets of Maricopa County, Arizona, and the rest of the nation.

I am not seeking to myself enforce the immigration laws as this is the province of the federal government. Rather, I am seeking to have the President and the other defendants obey the U.S. Constitution, which prevents this executive order from having been issued in the first place. This unconstitutional act must be enjoined by a court of law on behalf of not just myself, but all of the American people.”

I wondered if someone else could do it. Seems like all of us here legally have standing in the matter.

If nobody, even Presidential Electors (the people who actually cast the votes for President) had "standing" to sue over the Natural Born Citizen argument, then I don't see how anybody has any "standing" whatsoever to challenge anything the King does. This will be thrown out of the first court it sees, along with the several states that also file actions.
