(CNN) - Republican presidential candidate Michele Bachmann will meet later Wednesday with Maricopa County Sheriff Joe Arpaio.
The congresswoman from Minnesota is also holding fundraisers while in Arizona. The campaign tells CNN that the issue of illegal immigration is extremely important to Bachmann, as it is for Arpaio, who has been very outspoken on the issue.
Earlier Wednesday Arpaio tweeted that he would be meeting Bachmann. Last week he tweeted that Texas Gov. Rick Perry, the frontrunner in the national polls in the battle for the GOP presidential nomination, called him at home and that they discussed illegal immigration.
Bachmann is not the only Republican White House hopeful in Arizona Wednesday. Former Massachusetts Gov. Mitt Romney, who's making his second bid for the GOP nomination, is holding town hall events in the state.
Arpaio will be a guest on CNN's John King USA Wednesday night at 7pm ET.
