Of particular concern to Democrats: whether the White House will seek to use executive privilege to keep private any portions of Mueller’s report that addresses alleged obstruction of justice by the president.

There is a growing sense that the special counsel’s closely held investigation could come to culmination soon. Some Trump advisers think Mueller could deliver the confidential report explaining his findings to senior Justice Department officials next month. Under the rules authorizing the special counsel, the attorney general can then decide whether to share the report or parts of it with Congress and the public.

Some House leaders have vowed to immediately seek to obtain a copy of Mueller’s findings. But the White House would resist the release of details describing confidential and sensitive communications between the president and his senior aides, Trump advisers say.
