The man at the helm of the Democratic Party’s main organizing apparatus is beginning to crack under pressure, according to insiders.

Nestled in a New York Times story about the Democratic National Committee’s dire financials was the mention of an incident between chair Ken Martin, a junior aide and a cell phone. Martin, who is contending with $2 million of DNC debt and a shrinking list of allies, reportedly threw his phone “in a pique of frustration” earlier this month.

Although the Times spoke with half a dozen people familiar with the incident, none witnessed it firsthand. There was also some contention over “how aggressively the phone was tossed,” and whether it was aimed at the desk or the aide. However, the incident sparked a formal complaint to the DNC’s human resources department.
