Because Malik didn't get the free ride, no-show federal government job he expected when his brother was elected.
It took him 7 years to realize that if his brother buried him in some standard agency hole, with a $200,000 annual salary and a forever pension, someone might eventually find out and it would be one more crime the media would be expected to paper over.
As it is, once he's out of office, and all the pus starts leaking out, Barry has to rely on a GOP stooge to cover for him, like GWB did for the Clintons and Sandy Burger.
Amen! “I think we should move on.” - George W. Bush
