What a terrible day yesterday was for at least three big-deal leaders. And how instructive the resulting case studies in crisis leadership could be.

-Oscar Munoz suddenly became CEO of United Continental after CEO Jeff Smisek resigned and left the company. The problem is a federal corruption investigation involving the airline and the Port Authority of New York and New Jersey, which operates Liberty Newark Airport, a major United hub where 70% of departures are United flights. It’s intriguing that the investigation has somehow reached Smisek, a highly regarded Houston lawyer at Vinson & Elkins before he joined Continental as general counsel in 1995. But he’s not the leader in crisis now. Munoz is.

He must shepherd the company through a potentially damaging crisis of integrity. We don’t know how bad it could be, but several months ago the company retained the law firm Jenner & Block to conduct an investigation, which is never a good sign. That’s the firm that produced the report on Lehman Brothers’ finances after it collapsed and that General Motors hired to investigate its ignition-switch disaster.

Until yesterday, Munoz was CEO of CSX, the giant railroad; he was also, and remains, a United director. Now he must keep this potential scandal from becoming a distraction for managers and employees, even though it is apparently getting worse.

-Some 24 hours after saying she had no need to apologize for her use of a private email server while Secretary of State, Hillary Clinton apologized for it. “That was a mistake. I’m sorry about that,” she told ABC News. It’s safe to say that her campaign is now in crisis mode. Consider that also yesterday, the New York Times reported that a second intelligence review of her emails found that they contained highly classified information.

Plus, you may recall that former Clinton staffer Bryan Pagliano, who set up her email server, told Senate investigators last week that he would assert his Fifth Amendment right to avoid self-incrimination and would not answer their questions. This is not good, and yesterday it got worse when the two key committee chairmen involved, Senators Charles Grassley and Ron Johnson, offered him immunity.

But wait, there’s more. Reuters reported yesterday that the State Department is adding 50 staffers to the existing 50 who are sorting through the 30,000 emails that Clinton sent back to State, and helping with a deluge of Freedom of Information Act requests, many of them related to the emails.

The election is 14 months away, an eternity. Clinton could certainly get through this long before then. Or it could be devastating. She’s in a crucible now.

-And then there’s New Jersey Governor and presidential candidate Chris Christie. The federal investigation that brought down Smisek also involves former Port Authority chairman David Samson, a Christie appointee who resigned last year after news broke of a separate federal investigation involving him. He is still reportedly a Christie confidant. Another corruption story is the last thing Christie needs after the ridiculous Bridgegate affair, also involving Samson and the Port Authority, had died down. Not that Christie has much left to lose as a presidential aspirant. The latest poll shows him with 2% support, ranking 10^th among Republican candidates.
