From Yahoo News:
Attorney General William Barr refused Wednesday to turn over his notes on a conversation he had with Robert Mueller during which the special counsel complained about Barr’s summary of his report about Russian interference in the 2016 presidential election and Donald Trump’s attempts to cover it up.
“No,” Barr responded when asked by Sen. Richard Blumenthal, D-Conn., if he would provide the Senate Judiciary Committee with the notes he took to document the call with Mueller.
“Why not?” Blumenthal responded.
“Why should you have them?” Barr answered.
