The Osama plot to Kill Obama. Full Link to Bin Laden Document

The Osama Bin Laden Document as Released by The American Government.

"I asked Shaykh Sa'id, Allah have mercy on his soul, to task
brother Ilyas to prepare two groups -­ one in Pakistan and the
other in the Bagram area of Afghanistan -­ with the mission of
anticipating and spotting the visits of Obama or Petraeus to
Afghanistan or Pakistan to target the aircraft of either one of
them. They are not to target visits by US Vice President Biden,
Secretary of Defense Gates, Joint Chiefs of Staff (Chairman)
Mullen, or the Special Envoy to Pakistan and Afghanistan
Holbrook. The groups will remain on the lookout for Obama or
Petraeus. The reason for concentrating on them is that Obama is
the head of infidelity and killing him automatically will make
Biden take over the presidency for the remainder of the term, as
it is the norm over there. Biden is totally unprepared for that
post, which will lead the US into a crisis. As for Petraeus, he
is the man of the hour in this last year of the war, and killing
him would alter the war's path.
So please ask brother Ilyas to send to me the steps he has taken
into that work. 

It would be good if you coordinate with our brothers of the

Pakistan and Afghanistan Taliban in regards to the external
work, so that there is complete cooperation between us, and tell
them that we started planning work inside America many years
ago, and gained experience in that field, and we and they are
brothers so we should not fall into the error that hurts the
Muslims and benefits the enemy, due to lack of coordination
between us. So, for example, the operation of brother Faysal
Shahrazad, Allah release his imprisonment, was possible to avoid
his capture and the errors that happened easily by one who had
then travelled from America to Waziristan before the operation, it
would have made it difficult to capture the brother that fast,
and based on that, draw their attention to the importance of
cooperation among us and the possibility of the two sides
adopting the operation reduces the possibility of these errors,
after which the Americans commented that the Mujahidin have
become unable to conduct a large operation that is well planned.
You have to keep in mind the possibility, though remote,
that the journalists may be involuntarily monitored, in a way
that we or they do not know about, either on ground or by
satellite, especially Ahmad Zaydan, and it is possible that a
tracking chip could be put into some of their personal effects
before coming to the meeting place to conduct any business with
them, or to conduct an interview with one of the brothers, and
as you know Ahmad Zaydan has interviewed a number of the Taliban"
