D'Souza pleaded guilty in 2014 to violating campaign finance laws with an illegal donation to a GOP Senate candidate.
In 2012, D'Souza released his revelatory, investigative documentary 2016: Obama's America. "Then he got fired & I got pardoned", D'Souza tweeted at Bharara, former United States attorney for the Southern District of NY.
Unfortunately, that "perceived wrong" did not pertain to Alice Marie Johnson, a 63-year-old great-grandmother now serving a life sentence for a nonviolent drug crime and the reported subject of West's meeting with the president.
D'Souza once called on comedienne Rosie O'Donnell to be prosecuted for violating campaign finance laws in a fashion similar to his case.

D'Souza was sentenced to five years of probation, including eight months living under supervision in a halfway house and a $30,000 fine.
"D'SOUZA was sentenced today before U.S. District Judge Richard M. Berman", the statement said.
D'Souza pleaded guilty in 2014 over donating $20,000 to NY politician Wendy Long. "In light of these facts, the President has determined that Mr. D'Souza is fully worthy of this pardon", the statement said.
He has previously launched campaigns against both Obama and the then-presidential nominee Hillary Clinton.
The surprise pardon comes as the the Trump administration pushes criminal justice reform.
At issue is Article 40 of the state's Criminal Procedure Law, which, aside from certain exceptions, prevents state prosecution of crimes for which an individual has pleaded guilty or faced jury trial in any other jurisdiction, including federal court.
