Looks like tensions over business dealings at the Clinton Foundation haven’t soured the friendship between Bill Clinton and his former close adviser Doug Band. The two men, along with three others, were spotted at lunch at Sant Ambroeus in Southampton Thursday afternoon. Clinton’s family foundation has recently come under scrutiny after a report detailed its troubled finances and the foundation’s all-too-cozy relationship with Band’s strategic firm Teneo Group. Band’s firm stopped working with the foundation last year, but at one time Teneo charged the Clinton Foundation a monthly retainer as high as $250,000. A Clinton rep didn’t comment last night.
