White House admits of failures on the part of its own staff. WH protocol “was either deficient or mismanaged”

“After reviewing our actions, it is clear that the White House did not do everything we could have done to assist the United States Secret Service in ensuring that only invited guests enter the complex,’’ Mr. Messina wrote in the memo, posted on the White House web site late Wednesday afternoon."

White House Blocks Testimony on Party Crashers

The White House on Wednesday invoked the separation of powers to keep Desiree Rogers, President Obama’s social secretary, from testifying on Capitol Hill about how a couple of aspiring reality television show celebrities crashed a state dinner for the prime minister of India last week.
And the couple will not testify, either, according to a statement released late Wednesday by a public relations firm.
The statement says that the Virginia couple, Michaele and Tareq Salahi, have provided to the Secret Service and to the ranking members of the House committee conducting the hearing “all relevant e-mails and cellphone records that detail communications with a White House official,” and can do nothing else to help in the inquiry.
That evidence, the statement says, shows that no laws were broken, that White House protocol “was either deficient or mismanaged” and that there were “honest misunderstandings and mistakes made by all parties involved.” (continues here at NYT)
