1. The special counsel Robert Mueller, above, wrote a letter in late March to Attorney General William Barr, objecting to Mr. Barr’s early description of his investigation’s conclusions that appeared to clear President Trump, according to the Justice Department.

Mr. Barr defended his descriptions of the special counsel’s conclusions in conversations with Mr. Mueller over the days that followed.

The letter adds to the growing evidence of a rift between them and is another sign of the anger among the special counsel’s investigators about Mr. Barr’s characterization of their findings.
