After having spent has spent recent weeks at a breakneck pace, barreling through appointments for his Cabinet, the President-elect Barack Obama and his family arrived Saturday in his native Hawaii for a 12-day holiday vacation. Obama, his wife Michelle, and their two young daughters – Malia and Sasha - spent most of the 10-hour, nonstop flight from Chicago in the front cabin of the United Airlines plane.

During the past years, Obama and his family spent the December holidays visiting Obama’s maternal grandmother - Madelyn Payne Dunham - who died two days before Obama’s historic November 4 presidential win. Obama is expected to have a private memorial service for her.

According to the information from Obama’s aides, the Obama family would have no formal events during the trip. However, Obama will continue to have business meetings and intelligence briefings.

The low-profile Oahu trip of the Obama family was earlier interrupted with the release of an internal investigation about his aides’ roles in allegations of public corruption. An Obama aide told reporters that the review could be released early next week, but refused to discuss details, saying officials would honor prosecutors’ request to keep it private.

Though federal wiretaps include Illinois Gov. Rod Blagojevich using profane language to describe Obama, prosecutors say Obama and his team did nothing wrong.

In fact, Obama has expressed his eagerness to release their internal investigation regarding the kind of contacts his aides had with Blagojevich, who faces federal allegations he tried to sell Obama’s former US Senate seat to the highest bidder.
