According to the Salt Lake Tribune, O'Keefe's arrest has left the Salt Lake Country Republicans scrambling to find a new speaker.
"The allegations and arrest today certainly change our plans," county GOP Chairman Thomas Wright told The Tribune. "We'll be announcing a new speaker shortly."
The group's website has been scrubbed of references to O'Keefe, but according to The Tribune his speech would have focused on "his national exposÃ© of ACORN's unethical behavior, his changes in Congress and [how he will] inspire our Party's passion for a grassroots comeback."
Attendees to the dinner who paid more than $2,000 were eligible to attend a VIP reception with elected officials and the keynote speaker.
