Barr encouraged Paul to keep fighting "through whatever avenues he sees fit."
"Congressman Ron Paul has fought tirelessly in both the Libertarian Party and the Republican Party to minimize government power and maximize individual liberty," Barr said in a statement released by his campaign. "I want to thank him for all that he has done for liberty in this nation, and encourage him to continue his fight through whatever avenues he sees fit."
Paul ran for president in 1988 as the Libertarian Party's candidate, finishing third behind Vice President George H.W. Bush (R) and Massachusetts Gov. Michael Dukakis (D) with 432,000 votes.
