Longtime Bill Clinton aide Doug Band, who has appeared in Hillary Clinton emails seeking meetings and assistance for Clinton Foundation donors, put in a request for himself by seeking a diplomatic passport, newly released emails reveal.

Band, who assisted Bill Clinton for years and became a close counselor after Clinton left the White House, made the passport appeal to Hillary Clinton aide Huma Abedin, in an email released by open government group Judicial Watch Thursday.

The appeal apparently was a prelude to Bill Clinton's dramatic 2009 mission to North Korea to free two detained Americans, according to a source familiar with the trip.

'Need get me/ justy and jd dip passports,' Band wrote Abedin in a July 29, 2009 email.

'We had them years ago but they lapsed and we didn’t bother getting them,' he added.

Six minutes after the message was sent, Abedin replied, 'Ok will figure it out.'

The reference to justy was regarding Clinton Foundation aide Justin Cooper. Cooper, a senior advisor to Clinton who like Band also joined private consulting firm Teneo, helped set up the private Clinton server that ultimately led to the release of the emails.

A source said the request got made in advance of President Clinton's August 2009 trip to North Korea to seek the release of two Americans detained there, Lisa Ling and Euna Lee.

The 'jd' in the message refers to Justin Davidson, a lower level aide who ultimately did not go.

Band is the founding partner and president of Teneo, a firm that later provided Abedin with part time work as a 'special government employee' while she was still working at the State Department.

Other concurrent emails plead for Hillary Clinton face time with Andrew Liveris, the CEO of Dow Chemical. According to the source, these contacts occurred because Liveris was to provide the plane used on the Bill Clinton North Korea mission.

'Wjc wants to be sure hrc sees Andrew Liveris, ceo of dow tomorrow night. Apparently he is head of us china business council. Is he definitely going to be there?' Abedin wrote Clinton scheduler Lona Valmoro on July 27, according to the Judicial Watch release,' which contained initials for President Clinton.

'I will check. He declined our invitation to dinner tonight at State,' Valmoro replied.

'Yes pull aside on arrival,' Abedin ultimately consented.

Judicial Watch noted that Liveris donated between $1 million and $5 million to the Clinton Foundation, and said the emails contained 'additional instances of the Clinton State Department’s granting special favors to major contributors to the Clinton Foundation.'

The source said the plane and passport emails were part of a 'flawless mission' that led to the release of the Americans.

According to the United States Code, diplomatic passports are strictly limited to 'members of the Foreign Service, their family members, or those working on U.S. government contracts.'

'A diplomatic passport is issued to a Foreign Service officer or to a person having diplomatic status or comparable status because he or she is traveling abroad to carry out diplomatic duties on behalf of the U.S. Government,' the code states.

Family members of diplomats also get the special passports, which on occasion can be made available to U.S. government contractors if eligible and it is deemed necessary.

The passports may allow admittance to countries that ordinarily require a visa. They may also bring less scrutiny at airport security or at customs, but people familiar with diplomatic travel say diplomats are not considered immune from bag checks.

Diplomats also get to breeze through security lines.

On a mission to a secluded country like North Korea, a special diplomatic passport would allow a travel to avoid getting a stamp that might cause problems during future travel on a regular passport.

It is unclear the extent to which a diplomatic passport may grant some level of diplomatic immunity given to diplomats serving overseas. There have been cases where diplomats have committed crimes while serving abroad and used their immunity to try to avoid prosecution.

Band's overture to Huma for himself was the same track he employed to assist a major donor to the Clinton Foundation that was unearthed last week.
