Attorney General William Barr declined to appear before a hearing scheduled on Thursday before the House Judiciary Committee following hours of sometimes tough back-and-forth on Wednesday in the Senate.

Attorney General William Barr has released a redacted version of special counsel Robert Mueller's report on Russian interference in the 2016 election to Congress and the public.
