The 12-nation Pacific trade pact would create nearly a quarter of a million U.S. jobs due to increased foreign investment in the United States, a business group estimated on Monday, in the first look at the deal's employment impact.

The Trans-Pacific Partnership, a potential legacy-defining achievement for President Barack Obama, is near completion but has run into opposition from Democrats and others who worry the deal would cost U.S. jobs.

The Organization for International Investment (OFII), a trade group that represents the U.S. operations of global companies, said the TPP would create 68,000 direct jobs tied to an estimated $20 billion boost in foreign direct investment.
