They're accused of muddying county conventions in Colorado and Iowa last weekend.
In Iowa, a half dozen counties reported disruptions during conventions. The most egregious example occurred in Polk County, where Paul supporters illegally tried to become delegates.
"They were abrasive, offensive, and self-centered," said Kevin McLaughlin, GOP chairman in Polk County.
In Colorado, Ron Paul supporters shouted down Denver County GOP Chairman Danny Stroud, demanding rule changes in favor of their candidate.
"A small, loud group attempted to hijack the assembly and trample on the rights of those who took time out of their busy lives to participate in the political process," Stroud said in a statement to the Denver Post.
