The Washington Post, The New York Times, CNN, Politico and The Associated Press filed a joint motion on Tuesday asking a court to unseal affidavits, warrants and seizure records filed by Mueller's team, the Post reported.

The motion argues that the sealed materials could contain information of public interest and provide details about the direction of Mueller's investigation and the basis for FBI raids.

Some of the documents related to warrants obtained by Mueller have remained under wraps for several months — an unusually long period of time.

Mueller was appointed in May to carry out the criminal investigation into Moscow's meddling and any possible coordination between the Trump campaign and Russia, although his mandate gives him the authority to probe other issues that may arise from the main investigation.

Trump has repeatedly denied that anyone on his campaign conspired with Moscow to help sway the election, and has called Mueller's probe a "witch hunt" and a "hoax."
