A Senate committee is reviewing Facebook’s problematic stock offering amid questions about whether the bank handling the IPO gave select clients a negative assessment of the company.

A Democratic aide to the Senate Banking Committee said Wednesday that members want to know more about the initial public offering.

The aide said members of the Democrat-controlled committee want to meet with Facebook executives and regulatory agencies for an informal inquiry. The aide spoke on condition of anonymity because the committee’s planned inquiry hasn’t been publicly announced. . .
