Ron Paul's presidential campaign on Wednesday threatened to fight the seating of some Washington delegates to the Republican National Convention, saying there is a lack of transparency in how party officials from the state's largest county are chosen.

Paul's claim came three days before Washington's Republican caucuses on Saturday.

Kirby Wilbur, the state GOP Party chairman, said Paul's accusations are "baseless." A lawyer for Paul's campaign sent a letter to Wilbur and Lori Sotelo, head of the King County Republican Party. The Paul campaign said the King County GOP violated party rules by not revealing the names of certain party officials, known as precinct committee officers, who will take part in the caucuses.

"Their concern is that they appointed all these last-minute, anti-Ron Paul PCOs, but there's no proof," Wilbur told The Associated Press.
