Sen. Rand Paul, a potential 2016 presidential candidate, will be in Iowa for three days next month, with a stop in Davenport planned as well as a fundraiser for Republican congressional hopeful Mariannette Miller-Meeks.

During his Aug. 4-6 visit, Paul will take part in Republican party fundraisers in other parts of the state, as well as a fundraiser for Miller-Meeks on Aug. 5 in Iowa City.

"It is an honor to have Sen. Rand Paul join our campaign for an event during his visit to Iowa," Miller-Meeks said in a statement Tuesday. "We both know that the dysfunction in Washington is unsustainable and, as eye doctors, we understand it will take vision to get America back on track. Iowans need better health care reforms, higher take-home pay, and accountability in their government."

Miller-Meeks and Paul are ophthalmologists. She is challenging  Rep. Dave Loebsack, D-Iowa, in the 2nd District race.

Loebsack's campaign responded to the announcement Tuesday by saying Paul and Miller-Meeks are threats to Social Security and would gut education funding.

"The vision of Dr. Miller-Meeks working alongside Sen. Paul is hardly a sight for sore eyes and would mean a blurry future for Iowans," said Jennie Johnson, Loebsack's campaign manager.

Paul's visit here will be the latest in a string of stops to the state, which hosts the first-in-the-nation presidential caucuses.

The Kentucky senator has been strengthening his ties to Iowa. Recently, he hired Davenport native Steve Grubbs, a veteran of caucus campaigns, to lead his political action committee in the state.

He also has brought on former Republican Party of Iowa Chairman A.J. Spiker.

Grubbs said Tuesday that Paul would visit a business in Davenport on Aug. 5, although specifics weren't available.
