President Trump on Monday acknowledged he might watch some of Robert Mueller's testimony on Capitol Hill this week as he renewed his attacks against the former special counsel's credibility. Trump asserted that Mueller found "no collusion" in his report, issued earlier this year, and that Attorney General William Barr "was easily able" to rule that the president did not obstruct justice. "This thing should have ended a long time ago," Trump said. "This has been going on for 2 1/2 years, and we’re never going to allow this to happen again because most of them wouldn’t be able to take it." In a pair of tweets earlier in the day, Trump repeated his claim that Mueller is “highly conflicted” and accused him of leading a “ridiculous Witch Hunt.”
