Sen. Rand Paul

Republican Sen. Rand Paul of Kentucky. (February 14, 2014)

An organization aiming to "build the statewide liberty movement" in Maryland will host Sen. Rand Paul -- a Kentucky Republican often touted as a potential presidential candidate -- for a fundraiser next month.

The Maryland Liberty PAC, run by a conservative advocate with ties to the senator's father -- former Republican congressman Ron Paul of Texas -- will host the Kentuckian in Linthicum Heights on March 26. Ticket prices run from $30 to $5,000.

The group is run by Patrick McGrady, an occasional candidate for office in Maryland and a member of the Campaign for Liberty, a conservative group founded by Ron Paul that focuses on fiscal issues.

Rand Paul, a favorite of the Tea Party movement, beat a centrist Republican with establishment ties in Kentucky's 2010 GOP primary. He has frequently stood up for conservative causes in Congress. He made news earlier this week, for instance, for suing the Obama administration and the National Security Agency over controversial data collection programs.
