President Donald Trump may be guilty of many things, but a cover-up in the Mueller probe isn't one of them.
House Speaker Nancy Pelosi, attempting to appease forces in the Democratic Party eager for impeachment, is accusing him of one, with all the familiar Watergate connotations.
The charge is strange, not to say incomprehensible, in light of the fact that Congress is in possession of a 448-page report produced by the Trump Department of Justice cataloging the alleged obstruction that Congress now wants to investigate. The report is so exhaustive that many members of Congress haven't had the time to read it.
