It's been more than three months since Dubai Ports World agreed to sell its port operations at 22 U.S. ports. But as of today, all 22 of these terminal facilities remained under the control of Dubai Ports and the government of Dubai. You thought we weren't watching, didn't you? Bill Tucker reports.

BILL TUCKER, CNN CORRESPONDENT (voice-over): The bottom line of the Dubai Ports World deal is pretty easy to understand.

JOE MULDOON, FULLER & COMPANY: Since March 6th, Dubai Ports World has owned and controlled operations in 22 U.S. ports and that Congress now has dropped the provision that would prohibit their approvals.

TUCKER: The reference to Congress has to do with the House and Senate stripping out language, put in by the House, that specifically forbid DP World from owning or controlling operations in our ports. With the removal of that language, it's not clear if DPW even legally is bound to sell the properties. The announced agreement by Dubai Ports World to sell was voluntary.

But the Committee on Foreign Investment in the United States says "CFIUS does, in fact, retain the authority to bring the company back into the CFIUS process if it acts inconsistently with its announced plan to sell to a U.S. buyer." DP world, in a recent letter to congressional leaders, assured them that the sale is proceeding as planned, which seems to be reassuring Congress for now.

REP. PETE KING (R), NEW YORK: They are making the best faith effort to find an American buyer and that progress is being made.

TUCKER: But as of yet, there has been no formal offer to sell, which is known as a prospectus, from DPW.
