Special counsel Robert Mueller has asked the White House to preserve all documents relating to the June 2016 meeting at Trump Tower that Donald Trump Jr., Jared Kushner and Paul Manafort had with a Russian lawyer and others, according to a source who has seen the letter.
Mueller sent a notice, called a document preservation request, asking White House staff to save "Any subjects discussed in the course of the June 2016 meeting" and also "Any decisions made regarding the recent disclosures about the June 2016 meeting," according to the source, who read portions of the letter to CNN.
The preservation request is broad and includes text messages, emails, notes, voicemails and other communications and documentation regarding the meeting and any related communication since then.
A White House spokeswoman told CNN they don't comment on internal communications and the special counsel's office declined to comment. Ref. CNN.
