Donald Trump Jr. has turned over 250 pages of records to a Senate panel investigating Russian interference in the 2016 presidential election.
The Senate Judiciary Committee says it received the records Friday from President Donald Trump's oldest son, and received 20,000 pages two days earlier from the Trump campaign.
The content of the documents was not immediately clear, though Trump Jr. helped arrange a June 2016 meeting at Trump Tower that is of interest to investigators.
The committee is one of several congressional panels investigating potential ties between Russia and the Trump campaign.
Committee leaders have been in talks with Trump Jr. and committee chairman Paul Manafort about private interviews. The committee initially called for them to testify publicly, but lawmakers have since said they were negotiating the terms of their appearances.
Manafort gets search warrant
Also, a spokesman for President Donald Trump's former campaign chairman, Paul Manafort, says that FBI agents served a search warrant at one of his homes.
Spokesman Jason Maloni said Manafort cooperated with the agents as he has "consistently" done.
Manafort has been a subject of a longstanding FBI investigation into his dealings in Ukraine and work for the country's former president, Viktor Yanukovych. Special Counsel Robert Mueller is also investigating Manafort as part of his probe into Russia's meddling in the 2016 election and any possible collusion with Trump associates.
Manafort has denied any wrongdoing. He also has cooperated with congressional committees investigating the election interference. Manafort has turned over documents to the intelligence and judiciary committees in the Senate. Manafort led the Trump campaign for several months.
