You need some kind of attribution, some reference as to where the "fact" is coming from.
OK, on or about the 25th of October, Obama's official campaign website posted this statement:
When Barack Obama Jr. was born on Aug. 4,1961, in Honolulu, Kenya was a British colony, still part of the United Kingdoms dwindling empire. As a Kenyan native, Barack Obama Sr. was a British subject whose citizenship status was governed by The British Nationality Act of 1948. That same act governed the status of Obama Sr.s children. Since Sen. Obama has neither renounced his U.S. citizenship nor sworn an oath of allegiance to Kenya, his Kenyan citizenship automatically expired on Aug. 4,1982.

I take the above statement as an omission of fact, and I believe a court would too.
The other 'fact' saying Obama hiring law firms to to defend him I thought came from a reliable source, although I can't recall where. I'll bet my whole bank account that it's true. I don't know how anyone can conceivably doubt that Obama has not hired lawyers to defend him with an array of law suits heading his way.
Oops
ommission = admission
Some of our other Presidents also had parents who may have qualified as British citizens. The last I believe was Woodrow Wilson, whose mother was born in England.
