PORTLAND, Maine (AP) Maine’s top election official vows to continue his fight for documents from the Presidential Advisory Commission on Election Integrity on which he served.

Secretary of State Matt Dunlap said Monday that his legal team will go back to court to ask a judge to order the release of the documents.

Dunlap contends the commission violated federal law by denying him and other members access to key documents and excluding them from much of the commission’s work.

A judge ruled that Dunlap was entitled to the documents, but the commission rejected his request after Trump disbanded the panel last week.

Dunlap said Monday that he’s “not letting it go.” He wrote in a Washington Post op-ed that “the people have a right to know what their government is working on.”
