Axios reported that the Trump administration sued Alaska on Thursday to block certification of election results if incumbent Republican Sen. Dan Sullivan loses. Axios said the race has been marked by controversy.

The Hill reported that the lawsuit was filed Thursday in the U.S. District Court for the District of Alaska. According to The Hill, the suit argues that a win for Democrat Mary Peltola could be blocked. The Hill's report was written by Julia Mueller.

CBS News reported that the Justice Department is asking the federal court to block certification if Sen. Sullivan loses. Its summary says the incumbent would have won had "the other Sullivan's votes" been counted for him, but the summary does not explain that point further.

Axios reported that the race includes three named candidates: incumbent Sullivan, Democrat Mary Pelota, and retired teacher Dan Sullivan. Axios said Republicans accuse Democrats of "planting a candidate with the same name" to confuse voters.

The reports differ on the spelling of the Democratic candidate's surname. Axios wrote "Pelota," while The Hill wrote "Peltola." Neither summary says which spelling is correct.

Axios, The Hill, and CBS News each describe the filing as coming from either the Trump administration or the Justice Department. The available summaries do not describe a response from Alaska election officials or a ruling by the court, and none of them gives a date for a decision.
