Its not clear what HOA president is getting reimbursed for

I was Treasurer on the board and noticed in the financial report that the President was receiving reimbursement money from the association's funds I started an inquiry by asking questions, and for receipts covering these withdrawals. It ended up with me getting a letter (she personally handed to me at a board meeting) to cease and desist from inquiring about her reimbursement as she is being harassed by being singled out because past board members were never inquired about. My question is what can I do to pursue my concerns further?  Ohio
