The self-proclaimed toughest sheriff in America took to the witness stand Tuesday and continued his denials that he knew about corruption and mismanagement within his office, saying that he delegated many responsibilities to his former chief deputy.

An internal investigations shows that a former top deputy to Maricopa County Sheriff Joe Arpaio engaged in immoral conduct and violated a range of office and county policies.

A Maricopa County Sheriff's Office captain has filed a lawsuit against former Attorney General Terry Goddard and others over personal emails released to the public.

The U.S. Department of Justice and Attorney General Terry Goddard are both looking into possible criminal charges involving campaign finance violations by a Maricopa County sheriff’s captain and the fundraising group he created in 2008.

The Sheriff's captain who last year headed up a secretive political committee that broke campaign finance laws in its efforts to support Maricopa County Sheriff Joe Arpaio is threatening to sue the county for "emotional distress" and investigate county officials for federal crimes unless it pays him $75,000.

A Maricopa County Sheriff's deputy avoided a six-figure fine earlier this year for violating state campaign finance law, but he and others involved in the imbroglio may be facing criminal charges for their actions.

Maricopa County officials said they were caught off-guard last week when they learned employees of Sheriff Joe Arpaio had provided thousands of dollars to an unregistered political committee by authorizing the county to divert money from their paychecks.

The Arizona Republican Party last year returned a six-figure contribution that came from an unregistered political committee, but nearly all of that money ended up back in the party's coffers before November's elections. Four business owners gave the state Republican Party a total of $90,000 last fall, only days after the party was forced to return $105,000 to a group known only as SCA.

Joel Fox doesn’t seem to be getting anywhere by repeating an argument that his six-figure donation to the Arizona Republican Party last election cycle was not intended to influence an election.

The man who headed a group that gave $105,000 to the Arizona Republican Party shortly before last year’s primary election faces a six-figure fine for failing to comply with a judge’s order that he provide the names of his donors - though he did tell the Maricopa County Elections Department he would turn over the names of the donors if their identities would be withheld from the public.
