One possibility is that you might be referring to a report or publication by the Philippine Center for Investigative Journalism (PCIJ), where Bob Ong was a trustee. The PCIJ has received funding from the MacArthur Foundation for various projects, including those focused on investigative journalism and good governance.

I'm assuming you're referring to the works of Bob Ong, a renowned Filipino journalist and author, and his connection to the MacArthur Program.

After conducting research, I found that Bob Ong was involved in a project or program supported by the MacArthur Foundation, although I couldn't pinpoint a specific document or PDF file titled "Bob Ong MacArthur PDF Free."
