National Digest: No challenge to gay marriage licenses in N.M. Embattled San Diego Mayor Bob Filner (D) on Wednesday reached a tentative deal involving a sexual harassment lawsuit filed against him and the city. City Attorney Jan Goldsmith said a proposed resolution was reached and that it will be presented to the City Council during a closed session Friday. No details were released, and it was unclear whether a resignation was part of the deal. Mediation talks over the lawsuit filed by Filner's former communications director Irene McCormack Jackson have occurred over the past three days. The 70-year-old former congressman has been besieged by allegations from at least 17 women. Earlier Wednesday, a San Diego businesswoman, Dianne York, stepped forward to say the mayor had made unwanted sexual advances toward her. A petition drive to recall Filner is in full swing. The Democratic National Committee is planning to vote Friday on a resolution asking him to step down. No challenge to gay-marriage licenses State Attorney General Gary King said Wednesday he will not challenge a move by a county clerk to issue same-sex marriage licenses, because he does not believe New Mexico state laws prohibiting same-sex marriage are constitutional. King also said he will not challenge any other county clerk who issues licenses. Dona Ana County Clerk Lynn Ellins began issuing same-sex marriage licenses Wednesday after he said his review of state law allowed him to do so. Couples immediately began arriving at a Las Cruces courthouse to receive licenses amid pending court challenges elsewhere in the state. Ellins said 35 licenses were issued to same-sex couples Wednesday. Okla. school receives threat after killing of Australian: Public schools in Duncan, Okla., were on alert Wednesday after police received threats against Duncan High School following the arrest of three teenagers in connection with the killing of a university student from Australia.

A representative for Duncan High School declined to say if the suspects - Chancey Allen Luna, 16, James Francis Edwards Jr., 15, and Michael Dewayne Jones, 17 - attended that school. Arizona, Kansas sue U.S. election agency: Arizona and Kansas sued the U.S. Election Assistance Commission on Wednesday, seeking a court order forcing it to amend voter registration forms for those states so that people signing up are required to prove they are citizens. The states" complaint, filed in federal court in Topeka, Kan., comes two months after the U.S. Supreme Court threw out Arizona's law requiring such proof from would-be registrants. Writing for the majority, Justice Antonin Scalia said the state could petition the election commission to amend its form to add the requirement, which he said otherwise runs afoul of federal law.
