The caucus eve campaign stump will be at the University of Iowa

Washington (CNN) Former presidential candidate Ron Paul will make his first campaign trail appearance on Sunday to boost the White House bid of his son, Rand Paul.

The former Texas congressman will attend the "Revolution Continues Rally" at the University of Iowa in Iowa City, Iowa.

"Together they will focus on energizing the youthful base by discussing the importance of protecting the entire Bill of Rights and being boldly for conservative ideals that limit the powers of the Washington Machine," Rand Paul's campaign said in a statement Thursday.

The former Texas congressman came in third in the 2012 Iowa caucuses when he ran for president. In his 2008 presidential bid, he finished fifth, and he was also the Libertarian Party's presidential nominee in 1988.

More than a dozen Paul family members will host their own events throughout the state and speak at caucuses on February 1, the campaign said.
