A silly legal question from an armchair law aficionado: At what point does the wall between the White House counsel and the president's private, outside legal team come crumbling down? When will this firewall fail or be breached? Is it when Robert Mueller produces his report? Or could it be sooner, such as when the White House becomes involved in a cover-up or tries to obstruct the Special Counel's investigation?

Surely, it has to be when the White House gets involved in the cover-up of the 2016 Trump campaign's foreign collusion conspiracy?

We have heard the White House communications office use the phrase "outside counsel" quite a lot. Reporters are referred to Trump's private legal team for any questions relating to the Special Counsel investigation. But what happens when the White House Press Secretary lies in an effort to cover-up a detail in the alleged conspiracy between the Trump campaign and multiple foreign governments? Far more serious was the sighting of a White House lawyer at a classified DOJ briefing on the progress of the Special Counsel's investigation.

The White House counsel hasn't gotten much attention throughout Trump's first term, since most of the action has been conducted by his private legal team. But no matter how invisible or ineffective the White House team is, I think trouble is coming to them. Surely at leaast one of the fires Trump has set has gotten into our house. 

Sanders' lying at the podium, and Republican efforts to obstruct justice should bring the Mueller investigation into the White House. "Outside counsel" is going to have to become White House counsel. There can't be a wall between Mueller and the White House any longer.
