WASHINGTON (AP) — President Barack Obama signed off Friday on the first three — and possibly last — free trade agreements of his administration, deals with South Korea, Colombia, and Panama that could be worth billions to American exporters and create tens of thousands of jobs.

The three deals were years in the making, and the difficulty of bringing them to fruition make it unlikely there will be another bilateral trade agreement during Obama's current term.

Obama signed them with none of the ceremonial fanfare that normally accompanies such triumphs. Republicans, while supportive of the deals, continue to find fault with Obama's trade policies. And nearly three-fourths of House Democrats voted against the trade measures.
