Spicer may be the most high-profile domino to fall in the last 24 hours, but he's the third person in that time frame to peel away from Team Trump.
Trump's personal lawyer, Marc Kasowitz, who has represented Trump since 2000, is stepping away from taking the lead on all things Russia:
Marc Kasowitz, Trump's longtime personal attorney who has been the lead lawyer on the Russia investigation, will see his role recede, according to two sources with knowledge of the matter.
A third source said Kasowitz's role is changing because the needs are more Washington-centric and Kasowitz has done his primary job of putting the team together.
And with Kasowitz's receding role, Trump also lost his spokesman, Mark Corallo:
Corallo is a longtime GOP operative who worked for the House committee that investigated President Clinton in the 1990s before going to the Justice Department under former Attorney General John Ashcroft, according to Politico. Politico reports Corallo had been handling the White House's defense in the Russia investigation.
Who or what could be next? Things are clearly fluid and both Chief of Staff Reince Priebus and Trump aide Steve Bannon were reportedly aligned against the Scaramucci hire.
Naturally, Reince is already backing down, but his head’s been on the chopping block for months.
