WASHINGTON — Two congressional panels are reviewing Facebook’s highprofile stock offering last week amid allegations that the bank handling the IPO may have provided only select clients with a negative assessment of the company.

The chairman of the Senate Banking Committee, Sen. Tim Johnson, D-S.D., said late Wednesday that his panel wants to learn more about the social network’s initial offering. The banking committee seeks briefings with Facebook representatives, regulatory agencies and others.

After the briefings, Johnson said, he will determine whether a hearing should be held.

Also gathering information about Facebook’s IPO is the House Financial Services Committee. An aide to that panel said its staff is getting briefings.

The subject is likely to be raised in hearings by the committee in the coming weeks, even though no hearings are planned specifically on the Facebook IPO, the aide said.

Facebook began trading publicly on Friday on the Nasdaq.

Regulators are examining whether Morgan Stanley, the lead underwriter for the IPO, selectively informed clients of an analyst’s negative view of Facebook’s prospects before the stock offering.
