Judge questions Arpaio's truthfulness

PHOENIX (AP) - A judge presiding over an Arizona sheriff's racial profiling case has questioned whether the lawman testified truthfully about a secret investigation that critics say targeted the judge.
    
U.S. District Judge Murray Snow says Friday that he believes Sheriff Joe Arpaio was involved in his office's investigation that erroneously tried to show the judge was conspiring with federal authorities against the lawman.
    
But Snow says he's more concerned about Arpaio's truthfulness.
    
The investigation was examined in Arpaio's contempt-of-court hearings over his acknowledged defiance of court orders in the profiling case.
    
John Masterson, Arpaio's lead attorney, says the secret investigation isn't relevant to the contempt case.
    
Arpaio has denied he was investigating Snow.
