In the words of - but not necesarily endorsed by - Jeffrey Bales, a Member-at-Large of the Pima County GOP Executive Committee (Tucson, Arizona):
“Due to violation of the RNC's Rule #11, I call for Chairman Reince Priebus to resign immediately. It is un-American and beneath the standards established by the Republican Party to violate this rule. It is unethical to support a single Republican Presidential candidate (Mitt Romney) while other Republican candidates remain in the race.
"Further, I call upon Mitt Romney to denounce this behavior and ask that the RNC repair the breach of trust by including the other remaining Republican Presidential candidate, Dr. Ron Paul, in any dispensation of funds, effort and labor. It would benefit all Americans if Mitt Romney would further clarify the fact that 2 candidates remain if he challenged Dr. Ron Paul to a debate."
Rule #11 states:
"Rule No. 11 Candidate Support
(a) The Republican National Committee shall not, without the prior written and filed approval of all members of the Republican National Committee from the state involved, contribute money or in-kind aid to any candidate for any public or party office except the nominee of the Republican Party or a candidate who is unopposed in the Republican primary after the filing deadline for that office. In those states where state law establishes a nonpartisan primary in which Republican candidates could participate, but in which the general election may not include a Republican candidate, the candidate endorsed by a convention held under the authority of the state Republican Party shall be recognized by the Republican National Committee as the Republican nominee.
(b) No state Republican Party rule or state law shall be observed that allows persons who have participated or are participating in the selection of any nominee of a party other than the Republican Party, including, but not limited to, through the use of a multiparty primary or similar type ballot, to participate in the selection of a nominee of the Republican Party for that general election. No person nominated in violation of this rule shall be recognized by the Republican National Committee as the nominee of the Republican Party from that state."

This call for resignation is based upon statements released by the RNC on 4/25/12 that said,
“Governor Romney’s strong performance and delegate count at this stage of the primary process has made him our party’s presumptive nominee,” Mr. Priebus said. “In order to maximize our efforts I have directed my staff at the R.N.C. to open lines of communication with the Romney campaign.”
“It’s my intention to have a seamless and complete merger between the presumptive nominee and the Republican National Committee,” Mr. Priebus said. “That means political, communications, fund-raising, research and the chairman’s office, along with the governor’s main operational team, are completely merged.”
