[1] In 1983, she was appointed by then Governor Mark Wells White as the first judge of the then newly established 341st Judicial District, based in her native Laredo.
She set a record for longevity among the four Webb County justices serving in recent decades on the state courts, Districts 49, 111, 341, and 406, numbered in order of creation by the Texas Legislature.
[3] Ender is the youngest of three children of Oscar David Salinas, Sr. (1924-1997), and the former Elma Lopez (1922-2016), a native of Hebbronville, Texas, who was employed for many years by the Webb County tax assessor's office.
[5] "One thing about Mark White that some people may not remember is that he was very careful to appoint a percentage of individuals to commissions or to courts that reflected the population of Texas", she recalled.
She urged support in the 1990s for legislation sponsored by Lieutenant Governor Bob Bullock, which called for reduced class sizes in public schools and testing for learning disabilities.
Ender was among civic and political figures in Laredo who fought for the establishment of the four-year Texas A&M International University, located off the interstate loop named for Bullock.
In 2011, Judge Ender forbade the family of murder defendant Joseph Allen Garcia from observing the jury selection process in the case.
In 2013, after Ender had retired from the bench, the Texas Fourth Court of Appeals in San Antonio determined that she violated Garcia's rights under the Sixth Amendment to the United States Constitution by barring his family from observing jury deliberations.
