Attorneys for the state and Republican legislative leaders are asking a federal judge to throw out a lawsuit by Democrats challenging the way candidates are listed on the ballot.

A federal appeals court on Monday quashed an injunction that kept Arizona from enforcing a law designed to use the state's economic power to keep firms from boycotting Israel and companies that operate there.

Federal appellate judges have agreed to decide whether Martha McSally can continue to serve as a U.S. senator at least through the 2020 election.

Martha McSally can keep John McCain's Senate seat until at least the 2020 election, a federal judge ruled late Thursday.

Saying time is running out, the former chairman of the Arizona Libertarian Party wants the 9th Circuit Court of Appeals to order an election – and soon -- to decide who fills out the term of John McCain.

Claiming boycotts are anti-Semitic, the state House voted Monday to deny public contracts to firms that refuse to do business with other companies that do business in Israel.

Slapped down by a federal judge, a supporter of Israel is making a new bid to keep those who boycott the country and firms that do business there from getting government contracts.

In legal papers filed Friday, Brett Johnson, who is leading the legal team, acknowledged that vacancies in the U.S. Senate must be filled by a special election. But Johnson told U.S. District Court Judge Diane Humetewa that the U.S. Constitution allows the Legislature to let Ducey name a senator to serve until the next regular election.

Attorneys for the state want a federal appeals court to allow it to deny public contracts to those who boycott Israel, saying Arizona has a legitimate interest in denying support to the Palestine Liberation Army and its "unsavory -- and frequently murderous -- ends.''

A federal judge on Aug. 18 gave the go-ahead for a broad-based challenge to Arizona statutes that allow police and prosecutors to profit from items they seize.
