Charles Pierce of Esquire points out a big difference between the Watergate scandal and the attempted coup that led to January 6th:

As it happens, Tuesday was a kind of anniversary. On June 28, 1973, Senator Howard Baker, Jr. (R-Tenn) of the Senate Select Committee On Presidential Campaign Practices —the Watergate committee — began his questioning of former White House counsel John Dean, who had spent several days laying out with bloodless precision what would become known as “the White House horrors”. Baker asked the question that made him famous.

The central question at this point is simply put: What did the President know and when did he know it?

Nobody asked Cassidy Hutchinson that question. It was moot. The answer, as she spent Tuesday telling the committee, was “Everything” and “Immediately”.
