Special counsel Robert Mueller has tentatively agreed to testify on Capitol Hill on May 15, a member of the House Judiciary Committee said Sunday. Rep. David Cicilline, a Democrat from Rhode Island, broke the news on Fox News Sunday, the Washington Post reports. Among other issues, the committee—which reached the deal with a representative of Mueller—wants to hear whether Mueller believes Attorney General William Barr misstated the results of Mueller's investigation into Russian interference in the 2016 election campaign. (Mueller's report is a best-seller.)
