The Trump campaign has started giving documents to special counsel Robert Mueller as part of his investigation into Russian meddling in the 2016 election, according to a report.

Lawyers at Jones Day, the law firm representing the campaign, are locating the documents requested by Mueller and his team of investigators, sources told the Daily Beast. Some documents have already been turned over to the special counsel, who is leading the Justice Department's investigation into Russia's interference in the election.

Mueller is also looking into potential ties between Trump officials and Russia.

John Dowd, a lawyer representing President Trump, said the Trump campaign is in "total cooperation" with Mueller, and told the Daily Beast he has been turning over records to Mueller.

In addition to handing over documents to Mueller, the Trump campaign has also given documents to congressional investigators. Several congressional committees are conducting their own investigations into Russia's interference in the election.

The Trump campaign's executive director instructed campaign officials in May to keep all records and documents related to the campaign. Members of the president's transition team received a similar request in June from the transition's general counsel, which instructed staff and volunteers working on transition efforts to keep all documents related to Russia, Ukraine, and foreign travel by members of the Trump transition team.

The memo also instructed former transition team members to keep records related to former campaign chairman Paul Manafort, former campaign foreign policy adviser Carter Page, Mike Flynn, who went on to serve as national security adviser, and Roger Stone, a longtime informal adviser to Trump.
