WASHINGTON, DC, USA (AP) — President Donald Trump’s advisory commission on election integrity has integrity questions of its own — with some of its own members raising concerns about its openness.

This past week, two members fired off letters to commission staff complaining about a lack of information regarding the panel’s agenda and demanding answers about its activities. That comes as Democratic US senators are requesting a government investigation of the commission for ignoring formal requests from Congress.

The criticism from the commissioners was remarkable because it came from insiders — the very people who are supposed to be privy to its internal discussions and plans.

In a letter sent October 17, Maine Secretary of State Matthew Dunlap said it was clear he was not being made aware of information pertaining to the commission. He requested copies of all correspondence between commission members since Trump signed the executive order creating it in May.

“I am in a position where I feel compelled to inquire after the work of the commission upon which I am sworn to serve, and am yet completely uninformed as to its activities,” Dunlap wrote in his letter to Andrew Kossack, the commission’s executive director.

He said he had received no information about the commission’s research or activities since its last meeting, on September 12. He also said he continued to receive media inquiries about commission developments “that I, as a commissioner, am blind to”.

A commissioner from Alabama, Jefferson County, Probate Judge Alan L King, said he sent a similar letter late last week. He said the only information he has received since the commission’s meeting more than a month ago was an email informing him of the death of a fellow commissioner, former Arkansas state lawmaker David Dunn.

“Here I am on this high-level government committee, and I don’t know when the next meetings are or how many meetings there will be,” he said in a telephone interview. “I am in the dark on what will happen from this point on, to tell you the truth.”

King and Dunlap are two of four Democrats on the 11-member commission.

Requests for comment sent to Kossack, the commission’s executive director, and the commission’s vice-chairman, Kansas Secretary of State Kris Kobach, were not returned.

J Christian Adams, a commission member who was a Justice Department attorney under former President George W. Bush, said in an email that all commissioners were receiving the same information.

“Once upon a time election integrity was bipartisan,” Adams said in the email. “Apparently not all agree. That’s a shame.”

The commission has stirred controversy from the moment it was established last spring. Critics say Trump is using it to find support for his unsubstantiated claims of widespread voter fraud that cost him the popular vote during the 2016 election. Democrat Hillary Clinton received 2.8 million more votes nationwide than Trump.
