I'm intrigued by the first paragraph of Attorney-General William Barr's resignation letter. "I appreciate the opportunity to update you this afternoon on the department's review of voter fraud allegations in the 2020 election and how these allegations will continue to be pursued," Mr Barr writes. "At a time when the country is so deeply divided, it is incumbent on all levels of government, and all agencies acting within their purview, to do all we can to assure the integrity of elections and promote public confidence in their outcome." So, clearly Mr Barr met with President Trump today to discuss the Justice Department's review into allegations of voter fraud. This is what he said in an interview with The Associated Press two weeks ago: "To date, we have not seen fraud on a scale that could have effected a different outcome in the election." Have things changed since then? Or did Mr Barr spend today's meeting telling Mr Trump what he didn't want to hear?
