MICHELLE Obama gave her husband the silent treatment at one point in his campaign for president because so many women “pushed their bodies up against his, slipped phone numbers into his pockets” and whispered lewd suggestions in his ear, a new book out today claims.

In “Barack and Michelle: Portrait of an American Marriage” (William Morrow), Christopher Andersen reports, “On more than one occasion, Barack tried not to look startled when some random woman in the crowd would grasp him firmly by the derriere — and sometimes try to hold on.”

After an appearance in Peoria, Ill., the future president slid into the back of his SUV, and allegedly said, “Jesus, I wish they’d stop grabbing my ass.”
