Rep. Andy Biggs has joined two other Republicans on Arizona's congressional delegation in supporting a pardon for former Sheriff Joe Arpaio.
Like Republican Reps. Paul Gosar and Trent Franks, Biggs described the case against Arpaio as a political prosecution and supports a pardon.
Three Democrats on Arizona's nine-member delegation oppose a pardon.
The fourth Democrat said Arpaio should be held accountable for his actions.
Sen. Jeff Flake told reporters that he'd prefer to let the Arpaio case run its course.
Other top Arizona Republicans -- Gov. Doug Ducey, Sen. John McCain and Reps. Martha McSally and David Schweikert -- haven't publicly revealed whether they support an Arpaio pardon.
