Trump's G7 and trade adviser Kelly Ann Shaw departing the White House

Kelly Ann Shaw, the adviser to President Trump on the Group of 7 and trade policy who served as the U.S. "sherpa" for the G7 and G20 summits, told Reuters Tuesday that she's leaving his administration because she's ready for a "new adventure."

Why it matters: Shaw is one of the most senior women on Trump's economic team and was among those advising Trump during trade talks with China, Reuters notes. White House officials told the news agency she plans to exit her post on Friday to work in the private sector.

• The Trump administration had more departures than any other president in at least 40 years, and that trend seems to be continuing with John Bolton leaving his role as national security adviser last month amid chaos.

The big picture: The United States' plan to host the G7 next year has come under intense scrutiny since acting White House Chief of Staff Mick Mulvaney announced last week that the summit would be held at the Trump National Doral Miami resort.

• After bipartisan backlash, Trump tweeted on Saturday that his resort would no longer host the event — though he made clear then and since that he believes he has done nothing wrong.

What's next: Incoming national security adviser Robert O’Brien plans to cut the size of the National Security Council by "about a third in the coming months and limit its role in foreign policy," Reuters reports.

• It's unclear if Shaw will be replaced.
