A U.S. senator from Kentucky who's testing the waters for a presidential bid will venture across the Ohio River for appearances in neighboring swing state Ohio.
Rand Paul will speak Friday evening for the Hamilton County Republican Party's annual Lincoln-Reagan dinner. Before that, he'll participate in a school choice discussion at a Cincinnati charter school.
Paul has had a high public profile, speaking out against the National Security Agency on privacy issues and demanding information from President Barack Obama's administration about its drone strike policy. The tea party favorite also has been courting establishment Republicans.
He'll be joined in Cincinnati by Republican Sen. Rob Portman of Ohio, a strong 2012 supporter of Mitt Romney.
Paul has said he expects to decide on a presidential run after the November elections.
