Mitt Romney and Rand Paul met together Wednesday.
The one-on-one conversation in the nation's capital lasted 30 minutes. Sources say the tone was cordial but it wasn't meant to be an exchange of pleasantries. The Kentucky Republican focused his questions on policy.
Senator Paul is one of the GOP's rising stars. Many of his father's followers are wary of Romney, the presumptive nominee. Ron Paul has slowed down his campaign in recent weeks, but tension between the party's libertarian wing and Romney supporters remains.
