JUNEAU - Alaska Republican Senate candidate Joe Miller hasn't yet filed a required financial disclosure with the U.S. Senate Select Committee on Ethics, the office of public records said.
As of Wednesday, the office reported receiving disclosures from Miller's GOP rival, Sen. Lisa Murkowski, who's running a write-in campaign after losing the primary to Miller, and from the Democratic challenger in the race, Scott McAdams.
In an e-mail, Miller spokesman Randy DeSoto called the late filing "a simple oversight."
"We're already working on it, and it will be filed as soon as possible," he said without specifying when that might be. It also wasn't immediately clear whether any fees had been levied.
Candidates are to file within 30 days of becoming a candidate, after raising or spending $5,000. A missed deadline can result in a $200 late fee. If there's a chronic failure to file, the committee can meet to decide what action to take. Candidates face a potential penalty of up to $50,000 for failing to file or to report required information.
Miller announced his Senate run in April.
John Sassaman, the committee's staff director, said he couldn't specifically address Miller's case.
