Blow back: Jamie Dimon went on Meet the Press and said JPMorgan was "dead wrong" to dismiss early stories of the massive position in credit derivatives accumulated by the bank's chief investment office and the trader nicknamed the London whale. “We got very defensive, and people started justifying everything we did,” Dimon said.

Ina Drew, the JPMorgan executive who loves crisis, is expected to resign today after the bank lost more than $2 billion on a credit derivatives trade she oversaw. Achilles Macris, the executive who oversaw the London-based operation that placed the trades, and trader Javier Marin-Artajo, are also on their way out, the Wall Street Journal reports.

It appears the chief investment office's entire London operation could be dismissed.

Cover up: Who knows what would have happened if Yahoo CEO Scott Thompson had come clean about his resume from the start—in the end it was Mr. Thompson's lie about how the gratuitous degree in computer science first appeared that led to the executive's resignation.

Yahoo named Ross B. Levinsohn—its head of global media and the former News Corp. exec who presided over that company's $580 million takeover of MySpace—as interim CEO.

Meanwhile, Third Point Capital, which led the call for Mr. Thompson's resignation, will end its proxy fight after Yahoo agreed to give the hedge fund three seats on its board of directors, including one to Third Point founder Dan Loeb.

Activist investor Carl Icahn, meanwhile, is expected to disclose that he has taken a large stake in Chesapeake.

Filing looms, too: LightSquared executives spent the weekend prepping for bankruptcy court, after negotiations with lenders stalled. LightSquared, the wireless venture backed by Phil Falcone's Harbinger Capital, has until 5 p.m. today to reach an agreement with lenders.
