PHOENIX — Ruben Gallego is asking the state Court of Appeals to keep a legal lid on his 2016 divorce papers from ex-wife and Phoenix Mayor Kate Gallego. Documents filed with the court show that when the then congressman and now candidate for U.S. Senate filed for divorce while Kate was pregnant he took the case to Yavapai County even though the address he provided to election officials was in Phoenix. He also sought — and was granted permission — to seal the entire proceedings, not just the filings but even the fact that there was a case on the docket.
