WASHINGTON (Reuters) - President Donald Trump’s eldest son and former campaign chairman can testify publicly before U.S. Senate committees, Democratic Senator Dianne Feinstein told CNN on Tuesday. Feinstein said Robert Mueller, the special counsel investigating Russian meddling in the 2016 U.S. presidential election and possible collusion between Moscow and the Trump campaign, has said Donald Trump Jr. and Paul Manafort were free to testify. Feinstein is the top Democrat on the Senate Judiciary Committee, which is among the congressional panels pursuing Russia investigations.
