Attorney general nominee William Barr said Congress has the option of releasing parts of the report he will write on the final results of special counsel Robert Mueller’s Russia investigation, even if he decides not to release it himself.

Barr told senators in written responses to questions that a current regulation allows Congress to release his report on Mueller’s final product. He was responding to Sen. Amy Klobuchar, D-Minn., who, like other Democrats, is worried Barr would not allow his summary to be released.
