Anyone who's watched DONALD TRUMP'S desperate attempt to be considered relevant during the current political cycle is fully expecting his "large, bordering on gigantic" revelation about PRESIDENT OBAMA to be no big deal.

--But could it really be THIS insignificant???

--CNBC contributor DOUGLAS KASS claims that what Trump will reveal today is that MICHELLE OBAMA had DIVORCE PAPERS drawn up.

--Here's the catch, though:  They're probably from the year 2000 . . . almost 13 years ago.  Kass claims that Trump may have found the actual papers.  But the fact that they exist isn't really news.

-Author Ed Klein released a book earlier this year called "The Amateur", in which he claims Michelle was close to leaving President Obama after he lost his bid to win a House seat in Chicago.

--Supposedly, she was upset that he put their, quote, "stable and secure future" at risk over his political ambitions.

--This was about eight years into their marriage . . . and shortly before Obama's political fortunes reversed.  The Obamas celebrated their 20th wedding anniversary earlier this month.

--And for the record, they denied the claims in the book.

--By the way . . . there's also a claim making the rounds that Obama used and SOLD cocaine in college.  But a Trump advisor says today's announcement has nothing to do with that.
