We can begin with this video, which goes over the basic points:
Short version: Walpin was investigating Obama crony's involvement in an AmeriCorps-related scandal involving misappropriation of funding. Case was settled, to the mild detriment of crony*. Walpin disagreed with settlement. Complaint made against him. So far, this is all he-said, he-said.
Then the White House tried to force out Walpin; Walpin, well aware of his rights, made them go through the process. At this point, Senator Charles Grassley - Republican - stepped in, as IG issues are one of his interests. Grassley would also like to know if the First Lady's office is involved in this somehow, given that her CoS is going over to run the Corporation for National and Community Service, who Walpin was also responsible for oversight over. Meanwhile, Senator Claire McCaskill - Democrat - has also stepped in, as she too is usually associated with IG protection. That makes this officially a matter of bipartisan concern, which means that the White House of course is doing everything it can to address said concerns seriously.
I'm kidding, of course. No, what the White House is actually doing, of course, is trying to imply that Walpin's senile:
WASHINGTON -- Responding to criticism from a Senate Democratic ally, President Obama explained why he fired the Inspector General of the AmeriCorps without the 30-day notification required by law, calling Gerald Walpin so "confused" and "disoriented" that there was reason to question "his capacity to serve."
As Ed Morrissey noted, believing that this was the White House's primary motive requires that you believe that the administration's instinctive, immediate reaction to seeing an employee come down with a debilitating disease is to fire them. Yes. That is precisely the thing that one does when one wishes to maintain a reputation for empathy and tolerance. I can't say that I have as much difficulty as Michelle Malkin reconciling the allegation of Walpin's mental diminished capacity with his public appearances (see the video above), mostly because neither I nor Ms. Malkin can take it at all seriously...
*Nobody went to jail for misappropriating 850K. That makes it "mild" detriment.
