There was an event at Ohio State University earlier this year, featuring Ron Paul and Judge Andrew Napolitano, who was taping a segment of his Freedom Watch show for Fox News. The entire event is online on the Freedom Watch archive page.
The event was put on by the Young Americans for Liberty at Ohio State. Their March, 2010 quarterly report is online at the IRS website, and has the following organizational donor detail*:
Ohio Freedom Alliance: $1,000
WethePeopleUnderGod.com: $1000
Americans for Prosperity - Ohio: $1,000
Ohio Liberty Council: $3,000
University of Cincinnati: $1,000
Jacob Group,CPAs, LLC: $1,000
Out of $11,150 received, these six donors represent 72% of the total, and one of those donors is Americans for Prosperity. A visit to the Ron Paul Ohio website lists those donors as co-sponsors. A visit to the Liberty Alliance Ohio site confirms their role as a tea party organizer. (They're also publicizing the 2nd Amendment scary march on Washington, DC, but that's another story for another day).
Young Americans for Liberty is currently taking on "health care nullification", falling into lockstep with this month's tea party theme.
